Aradia Megido, also known by her Trollian handle, apocalypseArisen, is one of the trolls. The handle she uses alludes to two things within her life. One, "apocalypse", refers to the end of the world, which was a part of her. Secondly, "arisen", relates to the fact that she has died multiple times, but has managed to come back, or "rise from the dead" in a way. Her associated zodiac sign is Aries (♈) and she has curved ram's horns matching it.
Aradia is obsessed with temporal inevitability, and her motivations usually involve doing things solely because she knows they have to happen.
This is more or less true once Aradia achieved God-tier and is, officially, very much alive and intends to stay that way.She is enthusiastic and kind even when talking about depressing things. She is convinced that there is no reason to grieve, and thinks that things are going to turn out okay. Considering her knowledge of the time stream, it is likely that she knows some hopeful things later in the timeline.
