'Of old, if we wished to treat with the giants, we would travel to a great platform of stone in the mountains -- the Giants' Table. This was a place of peace, and neither Elves nor giants would raise a hand against the other while at the Table, no matter the troubles that stirred between our peoples. The Table fell into the snows long ago, but should still hold its old meaning to the giants.
'Journey to the Giants' Table and ask the giants why they have seen fit to break the ancient understanding that they would stay in the mountains. The Giants' Table is just south of the pass of Rakhâs-bizar, east of here and south, the companion to the guarded pass of Gabilazan. Do not enter Gabilazan, for dwarves of an unsavory sort have occupied the keep there and will not suffer you to pass. Rakhâs-bizar is further east of that guarded pass.
'If the giants do not respect the old ways, you will be in danger at the Giants' Table. Bring allies with you, just in case.'
Find the Giant's Table
Defeat the Giant-Elder
You found the Giants' Table, but the giants there attacked without warning. They have lost their respect for the old ways, and the Giants' Table is no longer a place of peaceful negotiation. You should return to Gwaemithrin with the news.
