The Dark One

When a small girl arrives at Aretuza, Tissaia takes her on as her first student and teaches her magic. An incident at the girl's Ascension night leaves her with no choice but to leave Aretuza.

Three centuries later, she returns to Aretuza with a man who claims to need her help. The battle of Sodden.

From the battle of Sodden, everything happens like the show. Parts will be missing and I'm not filling in the four year gap from Sodden to the Thanedd Coup.
