Worms haunt the northern reaches of Eorlsmead near Thinglad's edge.
'If you find yourself near the Teeming Nests where the worms roam freely, you should hew down as many of the menaces as you see.
'No good can come of those vile things being allowed to endure, and that is certain.'
Worms can be found at Teeming Nests to the north of Eorlsmead.
You should go defeat many worms in Teeming Nests to lessen the threat of attacks by the evil creatures.
Sabert stands at the gate of Stangard.
You should return to Sabert with news of your victory over the worms of the Teeming Nests.
