Excerpt from Kayde's Notes
Logan and I have a working theory that Arcanians were unwillingly involved in the Collapse - Logan witnessed a recording of raw magic extracted from Arcanians being used to cast an exceedingly powerful spell, and it seems likely that this spell triggered the Collapse.
(OOC) Also, if anyone wants to know more about Arcanians, both proven and theorized, you can ask me. I've got a LOT of notes written down on them. And the notes are bound to grow as things become more clear.
