Avatars have 3 major sets of files that make up their being; the Base Files, the Core File, and the Story File.
Base Files contain all the translated mechanics of the game and are generally the same across the board for all Avatars. It includes things like the ability to use chat windows, interface screens for crafting and using chests, the hotbar and status bars, voice chat, etc. It also contains the parameters for the basic pool of energy that each Avatar uses to sustain life functions and has enough emergency reserves for some special skill use. It’s not recommended to use too much as it will drain rapidly and risk the Avatar’s life.
The Core File is the soul of an Avatar, the thing that makes up who they are. It contains their memories and personality, and it holds a fragment of their Player’s soul to link back to the source and allows them to gain energy from their Player. The greater the sphere of influence the Player has, the larger the pool of energy the Avatar has to use for special skills and abilities. A Player’s soul has a limitation of having two Awakened Avatars anchored to them, a Main and an Alt, each with their own pool of energy to use.
The Story File contains an Avatar’s lore and is the thing that makes up what they are. These are what grants an Avatar special skills or abilities based on various factors, including their skin and whatever ‘story’ is thought up for them by their Player. This file set governs the Class, Type, Sub-Class, and talents for each Avatar. If the Player changes the lore for their Avatar, the Story File will update to reflect that and can alter the Avatar to match, even to the point of changing their physiology.
