Magic of Vesmir
The archivist is a strange codifier of magic. Instead of using spells, they depend on their significant knowledge in order to solve problems and aid their allies in combat. The saying is that “What has been is what will be, and what has been done is what will be done”, and the archivist turns this to power. Added to this immense knowledge is a significant amount of training in how to lead troops, and this is the school for leaders.
Tuck the halfling is the head archivist at Clearhaven. He is the only one of the heroes who decided to teach after the events in the wasteland. While he is getting well on in age, his knowledge and skill make him a natural leader. Every class has a story of some huge brute of a student attempting to defeat Tuck in hand to hand combat, and every class has a story of that student losing horribly to the halfling who’s bent double with age and unable to walk without a cane.
Note that this is the only class not taken directly from a book and is a mix of the archivist class from Heroes of Horror and the Marshall class from the Miniature’s Handbook.
