The Deepwood Memorial (4e)

tagline below title:
The PCs are sent to the long forgotten memorial of an Elven civil war.

from the Background:
Millennia ago, in a time remembered by none but long forgotten books, there was an elven civil war in the Deepwood. It began as a land feud between two elven houses and raged for 103 years. Both sides suffered many casualties. Finally, a great king rose to power and brought an end to the war. To be sure future generations did not forget the cost of civil war, the king had a memorial built as a reminder of the price paid in blood.
