Everything was so strange for a fabled being who had never stayed in another world other than his and although he had the help of a human who considered it funny having to teach him the things about their new world, he still felt like an outcast.
Santa Claus was already better but he still did not have his powers back which was one reason why he wasn't back in the workshop and away from all these strange behaviors and sometimes he worried about how his managers and the denizens of his workshop were faring. They probably thought him dead or captured by the gods or even the weaver and there was no way to communicate and let them know he was alright.
