Ser Gabrian

Ser Gabrian is an NPC who appears in a cutscene as your enter the Castle area of Gran Soren upon retriving the Confidential Letter for The Conspirators. He is just south of the gate entrance in an alcove just past the gate walls.

Ser Gabrian offers the Arisen a choice between giving him the letter, refusing and giving it to Fedel, or both. Through use of a forgery at The Black Cat, the Arisen may give Ser Gabrian the forgery and the real letter to Fedel. Giving both letters yields double the gold, experience, and rift crystals and unlocks the quest chain for both NPCs.

It appears that there is no impact on the story regardless of who the letter is given to. [unconfirmed]
