- “Ah, no offense, but your kings have some laws that don't make sense in a practical kind of world.”
Rogek does not seem to work on behalf of the Carta, but he still knows some of their secrets. He stands near the entrance to the Commons of Orzammar and will offer the Warden an opportunity to make some extra money through the Precious Metals quest. He asks the Warden to pay 50 for a shipment of Smuggled Lyrium to deliver to a man named Godwin in the Circle Tower, promising a "finder's fee" of 20 for bringing back Godwin's return order.
Instead of transporting the lyrium, the Warden can say "I'm going to turn you in" which will cause him to attack. During combat, Rogek prefers to stay in distance and use his crossbow while his men dual-wield and use rogue talents including Stealth.
If the Warden doesn't have enough money before they approach Rogek, they have to either kill him or decline. If his offer is declined he walks away and the quest can no longer be completed.
During Entering Jarvia's Hideout quest, Rogek is a another source of information on Jarvia, assuming that the Warden hasn't made a deal with him to smuggle lyrium and activated Precious Metals quest and hasn't left the position where he stands (which is possible if you reject his offer or not having enough money).If he is present and the investigation dialogue appears ("I'm looking for Jarvia. You got information to sell?"), you can offer to pay him 5, 15 or by accepting his 50 deal to smuggle lyrium, you can learn how to get into the Carta Hideout. The first selection will reveal next to nothing. With the second and third option, he will explain the use of "tokens" by Jarvia's men. This will also update your quest journal and trigger an encounter with Carta Thugs, allowing you an opportunity to obtain a Finger Bone Token. If you already have it, you can ask him about it to open up bribery options.
