A Feast for Crows
Torwold allied himself with Euron Greyjoy when Euron declared himself King of the Iron Islands. He is listed among Euron's supporters at the kingsmoot. As part of the plan to draw the lords of the Shield Islands away from the islands, Torwold and the Red Oarsman were sent up the river Mander with a dozen of the fastest longships by King Euron as bait and once the Shield lords began chasing he was to turn around and come back to the mouth of the Mander where the rest of the ironborn would be waiting. After the battle he was sent by King Euron to gather more supplies for the planned voyage to Slaver's Bay.
The Winds of Winter
Aeron Greyjoy is brought up from the hold of the Silence onto an island castle near the Arbor which has been captured by the ironborn. Several of Euron's captains are there feasting in the ruins of the castle, Torwald among them. They've killed the lord of the castle and all his kin, hanging them in the very hall where the captains feast. Aeron thinks of Browntooth as a creature near as vile as the Crow’s Eye himself, as he and the other captains all take turns taunting Aeron.
