Renewal at Crater Lake (5e)

From publisher blurb:

In the time before mankind, when the world was young, a blazing ball of fire split the sky and fell to earth with a thunderous roar...

Crater Lake Village, in the Blue Forest, is home to the reclusive Aergeth elves. Word has reached the surrounding communities that the elves are suffering from a strange illness and are in desperate need of help. The elves are master craftsmen who create crystalline arrowheads that are as dangerous as they are expensive. Some say the elves will reward those who are able to help them with a quiver of arrows each.

Renewal at Crater Lake is designed for 4–6 adventurers of 3rd to 5th level.
