OK, here's what I have gathered.
A long time ago, Sassan was the girlfriend of the evil Laiken. Laiken gave her a ring, I guess. To enter the Battle Tower, Laiken killed Sassan and used her blood to enter. He then took her ring and put it in his study, and bound her spirit to her grave, then pit a wind curse over it because she hates wind or something.
The Dragon Knight comes along, and dispels the wind curse. Sassan, who is dead and incorporeal, her spirit tells the Dragon Knight to bring her back her ring so she can come back to life.
The Dragon Knight brings Sassan her ring back, and she comes back to life. Not as a zombie, but as a living, breathing person... How exactly does that work? She was dead, but after bringing her ring back, she returns to life, no questions asked. Can someone (Larian) please explain that? Thanks.
