Ars Magica: Druesberg
Caelinus of Bonisagus
Departed senior magus of Druesberg
Caelinus was an elder magus, last survivor of the previous generation of magi at Druesberg. He was known to be a master of Auram magic, capable of raising winds and bringing down lightning bolts. He was also a student of astrology, and was often seen on the covenant roof making astronomical observations. His familiar was Vespertilia the bat.
Caelinus departed from the covenant in Autumn 1222, saying he was going on a pilgrimage to Bethlehem and would be back in one year. That was several years ago, and he has not been heard from since.
