Vartag Gavorn

Vartag Gavorn is a dwarf living in Orzammar and is the second of Prince Bhelen Aeducan. He's in the Chamber of Assembly in the Diamond Quarter in Orzammar.

Stealing
You can steal a Champion's Shield from Vartag, up to three times. Once when you first talk to him to get the quest to help Prince Bhelen at the Chamber Assembly, the second can be obtained if you complete the proving fights causing him to show up at the Proving Arena, and the third time after you've finished the quest and in the Royal Palace.

Quest
If you choose Lord Harrowmont over Bhelen, he remains at the palace after the coronation and will attack you the next time when you talk to him, accompanied by some guards.
