I'm not sure what the plans (if any) are for expanding the directions the game can move in, but as it stands it seems like the Encrypted Scroll is the key. You give it to Petrus to get the GC, you give it to the dude in the dungeon to get TX. If we continue that pattern it seems to me that it will get awkward pretty quickly to write in.
What I propose, is that the scroll itself always goes to Petrus. However, instead of immediately sending you into the GC, he then gives you permission to do errands for his courtiers while he confers with Haedlac. Chatting with him again gives the GC, while chatting with other people may give other quests. This opens up story possibilities without forcing the player to commit mail theft every time.
