Epilogue: Riddleport, here we go!

[Rosgakori]

SPOILERS, but only for OUR Group.

So. I have planned to play over an a epilogue, where Pc:s go back to riddelport. In there, their beloved Gold Goblin is distrained, and selled again forward, for a Halfling illusionist Jervin. Obviously, they want theirs back.

Spoiler:

There also is mr. Koon, dark naga merchant, who is disguised as a human and their leader, Count Morkon III, aristocrat-crimelord.

Here is the problem: What to do? I have the characters, and I believe they want theirs back, but what could be the best way to avoid the big general fight with these guys, and still make some nice plot? I have thoght something like this: They go in, try to bought it back, and fail in this. However, the manager (count) wants to meet them tomorrow. At the night, group of assasins try to kill them, obviously failing in progress. What happens after that, is bit of mystery. I dont want it to turn again for attacking the Gold Gobli, so how to avoid this? In short, how make an good, short, one-session-long, good-but-no-epic adventure for 14th level characters? I'm most grateful for your help!

Long live Asmodeus.
