Ars Magica: Druesberg
Drininkeana Ex Miscellenia
Magister of Life
A maga of the broken covenant of Calebais, whose lab the party explored. She barricaded herself into her sanctum but was slain by an assassin with a dagger. She had a collection of magically-preserved plants, and her magic appeared to be focused on plant life.
She wrote two books, which the party recovered from her study. These identify her as a member of House Ex Miscellenia and give her the title Magister of Life.
