The Shards of Kupoar
Magic is neither good nor bad. It's how you use it.
Gaius is a practitioner of healing magic and runs a temple that worships nature and balance between good and evil. He has had a run in with some undead creatures who attacked one of the scouts in his guard. The guard suffered a wound, which he died from, which Gaius was unable to cure. He is worried about a poison Lich summoning the dead and defiling the temples in the forest.
