Online:Battlegrounds

right
Battlegrounds are small-scale player-versus-player (PvP) gameplay that originally launched with the Morrowind chapter of ESO, but are now available to all players. Each battleground features a three-sided team setup with four players in each team, and you are able to queue up individually or in pre-formed groups. At launch, there were three battleground maps—a Foyada, a Dwemer ruin and a Daedric ruin—and three game types: Capture the Flag, Team Deathmatch, and Domination — but more were added in later updates. Battlegrounds feature leaderboards and have their own unique item set rewards.

Unlike in Cyrodiil, Battlegrounds are not Alliance-based. Instead, players can fight for the Fire Drakes (Orange), Pit Daemons (Green), or Storm Lords (Purple). Your team is assigned randomly on entering each Battleground.

Teams


Game Modes
Battlegrounds are divided intro three types, each with separate leaderboards:
Deathmatch: Find and kill enemy players to earn points for your team.
Flag Games:
Capture the Relic: Capture the enemies' relics and return them to your base.
Chaosball: Pick up and try to hold a ball which gives points but deals increasingly serious damage over time.
Land Grab:
Crazy King: Capture and try to hold capture points that will regularly move to different locations on the map.
Domination: Capture and hold sites across the map, continually earning points based on locations held.

Locations
Ald Carac: A dilapidated ruin of an ancient Dwemer city
Arcane University: A ruined outer district of the Imperial City, once Tamriel's center of magical learning
Ularra: An old overgrown Daedric worshipping site
Foyada Quarry: A quarry set in the shadow of Red Mountain
Mor Khazgur: An Orcish stronghold on the eastern slopes of the Druadach Mountains
Deeping Drome: A cavern containing a mysterious Dwemer ruin
Istirus Outpost: A fortification in southwestern Cyrodiil (allows mounts)
Eld Angavar: An extraplanar Ayleid complex floating in an otherworldly void (has two separate maps)

Rewards
As you participate in matches, you will earn points and medals based on the game mode. Points are earned for completing the game mode's primary objectives: killing enemies, capturing flags, defending locations, and holding the chaosball. Medals are earned for unique feats related to the game mode, including dealing damage, healing allies, performing kill streaks, capturing or defending flags, healing flag carriers, and taking damage.

Your points and medals contribute to your final rewards, including Alliance Points, Experience, and items, as well as your position on the battleground leaderboards. The top players on the leaderboards will receive additional rewards at the end of the week.

Repeatable Quests




Notes
A prototype battleground called Colovian Crossing, which featured a single, central capture point, was playable at many gaming conventions in 2014 and 2015.
The Repeatable Quests appear to be collectively repeatable as a group, not individually. You need to complete an open quest of this type before you can receive another from Battlemaster Rivyn. 
While in the battlegrounds, to enable PvP between the teams, your Alliance may be temporarily overridden. Fire Drakes become Aldmeri Dominion, Pit Daemons become Ebonheart Pact, and Storm Lords become Daggerfall Covenant. This override is usually hidden by the user interface, but can be revealed through use of Alliance-specific skills or items, such as Dragonknight Standard or the Alliance Rider Outfit.
The names of the battleground teams are a direct reference to   for TES:Arena. Arena was originally conceived as a fighting game featuring a tournament that took the player to each of Tamriel's cities to challenge different gladiatorial teams. According to a file from that stage of development left behind in the final game, the Firedrakes hailed from Torval, the Stormlords from Narsis and the Pit Daemons from Helstrom.
