Menvil

Menvil was one of Colbert's men during the attack on Agnes' village long ago. He was such a skilled user of flame magic that he could sense people simply from the temperature they emitted, accounting for his inability to see.

In the anime, he returns to seek revenge on Colbert for being the cause of his loss of vision. He kills Colbert while trying to kill Agnes, as Colbert was protecting her. He is killed by Agnes as revenge for helping to destroy her hometown.
