Disclaimer: All knowledge is 100% canon and taken from canon and/or extended lore sources, nothing is headcanoned or fanon. You may want to also check out the #DA Lore tag on the blog, as unofficial (somewhat unsourced) lore posts sometimes end up there that I want to source and make official eventually.
