Kurychek

Kurychek is an imp that assaulted the party in the elven quarter of Gate Pass. He appeared as a rat person at the carpentry shop where the party met Galaeron and Saphielle, and Rayland caught him in a bag.
He intended to capture the box that held Funzbar Biteknee's intel for The Lyceum, but was very clear that he ONLY wanted the box, not the contents necessarily. It seemed clear that he was summoned by a mage in Ragos, who was not very specific in their command to Kurychek.
The party captured Kurychek and brought him with them to the temple of the Knights of the Aquiline Cross. There, he made a deal with Jack - he would allow the party to rest, and he would not reveal his knowledge of the party's names or physical description, if they would give him the box at noon that day.
Kurychek is hilarious. He ends most words with a "z".
