Colaiste

The Colaiste is some sort of school in Rael. It isn't completely clear if it is available to everyone or if it's required, but it seems to focus primarily on the education of Raelech children. One of the most noted features of it is that it seems to provide combat (hand-to-hand, weapon-based, and war) training to all its members regardless of future prospects (based on the two people mentioning it being Fintan and Meara who noted how they did not use the combat training for the rest of their lives until they were thrust into it).
