The Angel's Game

The Angel's Game was the name used to refer to the battle between the two Riftlings known as the Dweller and the Creature. The exact rules of the Game are largely unknown, but it is known that the two sides took turns.
==The Pieces==
The Dweller: Played the Game whilst dwelling within his host "the Keeper". Because of arrangements made with his previous host, he was able to speak only through codes and puzzles. As such, he sent his Keeper and his allies various cryptic messages in an attempt to warn them of the coming danger.
The Keeper: Josh Rallus, the host chosen by the Dweller. Over time, he began to experience negative side effects of serving as the Dweller's host, culminating in him losing his sanity entirely when the Dweller was forced to use his energy during a confrontation with the Creature away from a Rift.
The Other: Austin Bradley, a friend of the Keeper whose main role in the Game was to be controlled by the Creature. He wore a bag over his head and carried a yarn doll around with him. In this state, he was also referred to as "Baghead" and the "UnWilling Watcher".
The Creature: A malevolent being that had supposedly battled with the Dweller for more than 10,000 years. He had a physical body constructed from the bodies of the dead in the image of the Slender Man. He used his energy to control the Other, as well as reanimate dead bodies which had been stuffed into garbage bags.
Several additional "pieces" were later added as the Game continued to change.
The Dreamer: Alana Hudson, a friend of the Keeper and the Other who had been having strange dreams around the time of the Game. The Dweller warned the Keeper to keep her out of the Game, but ultimately failed to do so. The name "Dreamer" may also refer to her being an optimist.
The Collector: Stephen Patrick, another friend of the Keeper. His role was to "pick up the pieces" after the Dweller had finished off the Creature. However, as the Game did not go as the Dweller planned, he later stated that there was no longer any need for a Collector.
Emet Rotter: The result of Josh and the Dweller combining into one being. He was said to be a vessel for spreading the Dweller's influence, and attempted to finish the Game by defeating the Other and the Creature himself.
In a Facebook chat on March 31st, 2011, UnWilling Watcher stated that the Game now involved nearly 7 billion pieces, implying that the whole world was now at stake.
==Collector's Game==
Mr. Collector later started a Game of his own, upon discovering the existence of Stephen and his friends in an alternate universe. Mr. Collector decided to kill them all, although he gave his followers the opportunity to vote on one individual for him to keep alive. The six who were involved in his Game were Joshua Harris, Austin Bradley, Alana Hudson, Stephen Patrick, Courtney Gray, and Tyler Greene. As the Game evolved, Collector abandoned his plans after killing Tyler, who he later confirmed had not one the vote. The Game later to came to revolve around five new players, with the objective of activating Phase-3 to further their own personal goals.
* The Reborn: The result of Emet Rotter assimilating the Dreamer and Joshua Harris.
* The Creature: The adversary of the Dweller during the Angel's Game, now possessing the body of the Other and wearing his blood-stained bag over his head.
* The Collector: An entity that had been born when Emet left some of the Dweller's power in Stephen Patrick, which then assimilated his mind as it grew.
* The Outcast: The Tyler Greene of the universe from which the Collector came, now indoctrinated by the Slender Man.
* The Damned: Austin Bradley, who had allied himself with the Collector after the death of his sister at the Creature's hands.
