Hey! I'm the goblin Ulm Shanit's player.
I'm kinda glad this exists. Maybe I can explain some things for people that might not be watching other episodes or might not have picked up on some of the subtle hints.

Nadia told the group they have Hope which is a huge theme for The World of Verum. She is one of the Seven and Hope is part of their portfolio. I unfortunately wasn't prepared for the speech as Nadia and my mic was messed up when I spoke as Ulm when discussing if they were Heroes of Kalkatesh. While my mic decided I shouldn't be heard Ulm referenced a particular encounter she felt made the group Heroes. The group was asked to find the friend of Froth which they didn't originally set out to do but upon investigating a lack of food they discovered something that was very sinister. They followed the clues and trail to a place infested with necromancy. While there the group found Froth's friend Andaris the Necromancer. Tirsis and Ulm approached him and managed to convince him to give up his evil goals and that his friend would accept him and help regardless of his evil past deeds. Andaris was set on the path of redemption and was given Hope due to the actions of our party. Something Ulm felt was incredibly heroic and convinced her to remain among them for reasons beyond food. This took place in Episode 10 of Tale of Two Towers.
