Sage here with a returning puppet! This here is Prince Andivad of the Goblin Kingdom! He's what happens when a strong-hearted girl and her Goblin King actually wind up married and having a baby. I had some CR with him a while back, but until Mandy gets herself situated and her ducks in a row, I'm not going to say one way or another if his paramour is or isn't around. :3
But what does this mean for you, the others of UTR? Well hey! Now we have access to the Goblin Kingdom, and ostensibly, other realms of the Six Kingdoms, provided Andy feels like pointing out how to get there, which is unlikely because he rarely feels like being genuinely helpful. It also means that there are going to be goblins (of the Henson/Froud persuasion) popping up in unexpected places. Feel free to have your characters wonder why their sock drawer is giggling, etc. It's a biproduct of goblin royalty being around, after all.
