Question: What are the event arrangers called for the genre of games Dagorhir Battle Games is part of?

full_context: Document 1: Melee weapon: A melee weapon is any weapon used in direct hand-to-hand combat; by contrast with ranged weapons which act at a distance. The term "melee" originates in the 1640s from the French word "mêlée ", which refers to hand-to-hand combat, a close quarters battle, a brawl, a confused fight, etc. Melee weapons can be broadly divided into three categories:
Document 2: Live action role-playing game: A live action role-playing game (LARP) is a form of role-playing game where the participants physically act out their characters' actions. The players pursue goals within a fictional setting represented by the real world while interacting with each other in character. The outcome of player actions may be mediated by game rules or determined by consensus among players. Event arrangers called gamemasters decide the setting and rules to be used and facilitate play.
Document 3: Social interaction in MMORPGs: Social interactions in MMORPGS take the form of in-game communication, virtual behaviors, and the development of interpersonal and group relationships. In "massive multiplayer online role-playing games" (MMORPGs), cooperation between players to accomplish difficult tasks is often an integral mechanic of gameplay, and organized groups of players, often called guilds, clans, or factions, emerge. Sometimes the relationships players from within the game spill over into friendships or romantic relationships in the material world. In other instances, romantic partners and groups of material world friends find that playing together strengthens their bonds.
Document 4: Star Wars Roleplaying Game (Fantasy Flight Games): The Star Wars Roleplaying Game is a tabletop role-playing game set in the "Star Wars" universe first published by Fantasy Flight Games in August 2012. It consists of three different standalone games, each one conceived to play a particular type of character:
Document 5: History of live action role-playing games: Live action role-playing games, known as LARPs, are a form of role-playing game in which live players/actors assume roles as specific characters and play out a scenario in-character. Technically, many childhood games may be thought of as simple LARPs, as they often involve the assumption of character roles. However, the scope of this article concerns itself mainly with LARPing in a technical sense: the organized live-action role-playing games whose origins are closely related to the invention of tabletop role-playing games in America in the 1970s.
Document 6: SCA armoured combat: SCA armoured combat, or informally heavy combat, is a combat sport developed by the Society for Creative Anachronism (SCA) in which participants in protective body armour either "act out" mock combats loosely inspired by forms of historical combat practiced in medieval Europe or under supervision, may approximate historically real combat using SCA approved safe weapons under the watch of marshals to maintain safety. It is variously considered a combat sport, contact sport, or a form of martial art.
Document 7: Dagorhir: Dagorhir Battle Games is a Live action role-playing game (battle game) with full-contact melee fighting and ranged combat as its primary focus. Fighters typically use foam weapons such as swords, flails, spears, bows and arrows, javelins, axes, and other medieval weapons. Participants wear period costume and are expected to stay in-character during events, although the amount of seriousness the role-playing aspect receives varies greatly by unit and chapter.
Document 8: International Medieval Combat Federation: The International Medieval Combat Federation, (IMCF) is a global historical full contact sport fighting revival movement, in which combatants use historically accurate reproduction medieval and early modern armour and blunted weapons to engage in competitive fights according to authentic historical tournament rules. Founded in 2013, the organisation now attracts hundred of fighters from 26 countries at various fighting competitions around the world. Most events are open to the public and major competitions are regularly seen by tens of thousands of spectators. The league holds dozens of smaller events throughout the year as well as a world championship competition in which national teams, selected from local or regional clubs in their respective countries, assemble at a suitably historical venue to compete. These events take the character of a medieval tournament, with historical attractions and exhibits beside the competition, as well as market stalls selling historically-themed foods, goods and souvenirs. Competing teams are billeted in reproduction medieval camps and must wear authentic clothing. Somewhat unlike the medieval competition, fighting is exclusively on foot, and strict rules are enforced to ensure the safety of competitors and fairness in the competition. The fighting can be between individuals or teams of up to 16 fighters per side.
Document 9: Battle gaming: Battle gaming is a North American medieval combat sport where participants use mock foam-padded weapons (boffer) in live action battles. The sport began in 1977 with the creation of Dagorhir.
Document 10: Theatrix (role-playing game): Theatrix is a role playing game produced by the defunct Backstage Press and no longer in print. Primarily diceless, the game includes rules for using dice to resolve actions. The game applies cinematic concepts to role-playing-- the players are "actors" and the GM is the "director." The games attempts to frame adventures in the model of screenplays, which have a structured plot consisting of a number of agreed upon acts, scenes, and "pinch-points". Players use plot points to guarantee success of an action or take minor control of the story. This was a relatively new and controversial concept being championed by few in mainstream RPGs at the time of its release. In addition to their numerically-rated attributes and skills, characters possess non-numerically-rated personality traits, and unrated 'descriptors'. Descriptors can act as advantages, but in order to use them so, the player must spend plot points. They can also act as disadvantages, and when they do so, the player gains plot points. The game encourages collaborative roleplaying, using what it calls "Distributed Directing", whereby the players may introduce subplots though the GM remains responsible for directing the main plot. Theatrix has many methods of resolving action and conflict without dice. Most notabable is the use of extensive flow-charts, printed on card-stock.
Document 11: Player character: A player character (also known as PC and playable character) is a fictional character in a role-playing or video game whose actions are directly controlled by a player of the game rather than the rules of the game. The characters that are not controlled by a player are called non-player characters (NPCs). The actions of non-player characters are typically handled by the game itself in video games, or according to rules followed by a gamemaster refereeing tabletop role-playing games. The player character functions as a fictional, alternate body for the player controlling it.
Document 12: Foam weapon: A foam weapon, (also known as a boffer, padded weapon, or latex weapon), is a padded mock weapon used for simulated handheld combat. Such weapons are used in simulated battles called battle gaming and in some live action role-playing games (LARPs).
Document 13: Belegarth Medieval Combat Society: Belegarth Medieval Combat Society is a full contact battle game where foam weapons are used in order to prevent serious physical injury to participants. It differs from other battle games and LARPs in that it is entirely combat-oriented that allows hard hitting, shield bashes, and grappling with little emphasis on role playing and has no magic or character classes. It is composed of a number of not-for-profit "realms", which compete at regional and national events every year. Typically, each realm also holds individual fighting practices several times a week. Realms vary in size from just a handful of people to over a hundred fighters.
Document 14: Role-playing video game: A role-playing video game (commonly referred to as role-playing game or RPG, as well as computer role-playing game or CRPG) is a video game genre where the player controls the actions of a character (and/or several party members) immersed in some well-defined world. Many role-playing video games have origins in tabletop role-playing games (Including "Dungeons & Dragons") and use much of the same , settings and game mechanics. Other major similarities with pen-and-paper games include developed story-telling and narrative elements, player character development, complexity, as well as replayability and immersion. The electronic medium removes the necessity for a gamemaster and increases combat resolution speed. RPGs have evolved from simple text-based console-window games into visually rich 3D experiences.
Document 15: New Zealand Live Action Role Playing Society: The New Zealand Live Action Role Playing Society, Inc. (NZLARPS) is a not for profit organization that supports Live action role-playing games in New Zealand. Formed by a collection of larpers in Auckland in 2006, NZLARPS has grown to encompass around 150 members, with chapters in Auckland, Wellington, and Hamilton. NZLARPS mainly serves as an umbrella organization within the New Zealand LARP community, aiding its members in the designing and running of events and providing funding and equipment.
