You have all been contacted by representatives of king Gareth Dragonsbane. The couriers tell each of you that an old library of the Witch-King Zhengyi has recently been unearthed. You are to explore the ruin and retrieve any spellbooks you find. Anything else is yours to keep.
On the apointed day you all gather at the Bloodstone gate. An old man greets you there. His whispy white hair falls on a simple white tunic. He carries nothing save a walking stick and two rings. "Greetings," he says, "you have each been contacted to serve our king. Although some of you," he pauses and glances at Derrat and Iago, "are of questionable honesty I believe all will be well. Here is a map. You are to bring back any spellbooks you find. If you cannot retrieve them make sure they are destroyed. Here is a map but be warned, Zhengyi was a powerful lich. There is no telling what he may have left behind." ((He hands you a map of the Bloodstone lands with the library marked on it. It looks to be about a day or two's worth of travel. If nobody has any questions you can set out immediately if you like.))
