A Past Forgotten, A Life Remembered

An old book of spells, a forgotten guild, a remembered brother, a war against the dark wizard himself and a race to defeat him, returning what was lost before there's no going back.

WARNING; may contain spoilers for those who don't know END's identity. Also, the past will not be 100% canon/official, it's my own version of it; 'plot' sure is convenient when you want a reason to alter something, haha:)

One more note...or more?:
-my sincere apologies for the grammar/ spelling mishaps, and potentially OOC (out of character) characters.
-will be first perspective, but from multiple people.
-was supposed to be a one shot, until it got too long, so sorry if it may move along a little faster than usual stories.
-chapters will be of varying length.
