Aurelius Aestivus was born Raduz, to Aurelius Medice Bonisagi and Ramune Dýemmadcera, while his father was discipulus to Auspecius Bonisagi. When his Gift was discovered, Auspecius decided to claim Raduz as his second discipulus.

Aurelius spent most of his apprenticeship on Arx Caeles, and has visited far distant lands. He wed Solveja, ward of Yarok and adoptive daughter of his grandmother Dýemma, in 1268 AD. As he and his family are pagans, he seeks a home where they can live without hassle.

Aurelius resides on Planum Sanctorum with his wife Solveja and their children. He speaks Czech and Latin.
