The Guild Master - Barnabas.

A lot of people didn't know it, but this guild master wasn't always a guild master. At some point in the past, he lived in the castle and he was one of the soldiers that was in charge of fighting for and protecting the former king of the kingdom. After the dragon wars ended and everything fell apart in the kingdom, all soldiers and servants left the castle because there was no need to protect an empty throne. This man was one of the very only people that didn't leave the castle. He stayed behind and took care of young Elias and Eliss until they were teenagers and then he finally had to leave as well.
