An access-quest called
A Foul Wind drops from Antonican Stags in Archer Woods. Upon completing this quest, you get access to Firemyst Gully and a Dwarf there will give you a quest called "
The Cleansing of Firemyst Gully".
The reward for completing the cleansing is a choice of weapons, one of which is a
Dwarven Maul of Cleansing - a very cool weapon that will last you long into the 20s if you don't mind using a 2H-weapon instead of a 1h/shield-combo.
Note: You have to
complete A Foul Wind by level 20, though. Possibly the cleansing too, but I'm not sure. With a full team, that will be a good adventure anyway in the very late teens.
