Raissa's Memory is a tome found in Act V of Diablo III. Written by Raissa, it is dropped in Lair of the Prophet when the spark of Raissa's soul is touched. Obtaining the journal will add to the People Finder achievement.
It reads as follows:
The Prophet asked each of us in turn, before he cast the spell of binding. Our lives for hers. If we declined, we could leave without any thought of shame. We each heard the question and answered the only way we could. Our cause was too important to not make that sacrifice.
Raissa the Enchantress
