Holy Moly, A lot has happened.
Now, I don't think i've ever clarified what Watcher spirits can do. But basically; 1. Watchers retain any magical power they may have had in life. If they didn't, They automatically gain whatever magical ability would suit their personality based off of the original EA Project. 2. Watchers can actually collide with objects at will, But Default to not being able to. This goes too for floating. 3. Watcher spirit's consciousness is never lost. Upon a watcher spirit "sleeping", They astral project. 4. Watchers still have the ability to perceive time, Unlike other variants of spirits. Hacc and many others really hate this, And Hacc has tried ending their afterlife because of this due to their memories weighing down on them for basically ever.
