DD:Find a Solution to the Plague Problem in Rivertown

Find a Solution to the Plague Problem in Rivertown is a Divine Divinity quest initiated in Aleroth.

Find a solution to the plague problem in Rivertown.
A young knight called Seth told me that people are dying because of a mysterious plague in Rivertown. I must try to find a cure for the plague before it spreads to other towns within the Dukedom.

An escort for the healers.
The healers are needed in Rivertown to help combat the plague, but the woods around Aleroth are swarming with orc raiding parties. The healers refuse to travel to Rivertown because of this danger. I need to get to the army commander and ask him to dispatch an escort.
