Kill 15 Mosshide Gnolls and 10 Mosshide Mongrels, then return to Rethiel the Greenwarden in the Wetlands.
The Mosshide Gnolls have lived in the Wetlands peacefully for many years, but now grow in numbers. Their feet stamp flat the fen's bushes and flowers, and their foul axes cut too much wood to fuel their fires.
They are no longer in balance with the land. For the Wetlands to survive, the Gnolls must be reduced.
Kill 15 Mosshide Gnolls and 10 Mosshide Mongrels. Hunt them to the south, near the Dwarven gate of Algaz. After you do this, return to me.
