The banks of the rivers that surround the Angle are home to deadly avanc. Deadly... and hungry.
'My scouts have returned with reports of dangerous creatures lurking on the shores of the local rivers. Since you will be heading in that direction on Glatharn's foolish errand, why not see what you can do to dispose of the creatures?'
Riverside avanc can be found along the banks of the rivers in the Angle.
Thalathril has asked you to dispose of the deadly avanc who plague the river-banks.
Thalathril is located in Tham Lumren, in the northern Angle.
You should let Thalathril know that you have disposed of many riverside avanc.
