My character's name is Chari (Chari the Chaotician to be exact!). I led several people into many great places of peril to retrieve the reagents required for this tome only to of collected them all and the quest not accept them. I died many times with the reagents in my inventory; and they were switched between various members of my party. So that may be while they were considered invalid in the end.
Chari - Male - Wizard - Gnome - Conjurer
Note: This quest is awesome for player initiated events. The people who came along with me on our adventure said it was very intense and enjoyable; all without the presence of a DM. So two thumbs up for whoever created this quest.
I did it as Pauric Ders once, didn't work, Alyssara had to "manualy" complete the quest for me. I did not die, nor switch items from my inventory.
