Romulus Wolfsbane

Romulus Wolfsbane was a teacher at Solaris Academy of Witchcraft and Wizardry (teaching Potions and later Defense Against the Dark Arts), the former Head of Dragon House and the older twin brother of Remus Wolfsbane. He was born to a beastman father and a Muggle human mother, who lived with the peaceful beastfolk in Mintos.

Romulus taught Defense Against the Dark Arts at the Ferolia Institute of Sorcery for four years, but moved to Solaris after being offered to replace Potions teacher/Head of Dragon House Jimmy Wormwood (who would return in Carl's sixth year). During the attack of Cyber-Varius, he was sacrificed by his former student to summon the Bahamut.
