Actually, the name of the item, if I remember, is Noble's Seal, NOT Noble's Crest for the reinforcements quest. If you review the quest under Collar of the storm neck item, it relays the entire quest but does NOT include the portion to resolve the Seal. I think this is still an incomplete portion of the quest or perhaps it hasn't been solved as of yet.
I am tempted to try and give it to Tormax. I am ally with all three giant factions and I will report my results under the other thread
