Felendren the Banished
Felendren the Banished is a Sunstrider Isle outcast in the Warcraft universe.

He was a blood elf that resided in the Falthrion Academy. However, he failed to control his magic addiction and became a wretched and a shell of his former self. He was banished for ignoring the warnings of the Academy teachers. Felendren later takes control of Falthrien Academy and has Arcane wraiths and elementals as his minions. However, an adventurer killed all of his minions and confronted the elf in his tower. The adventurer killed Felendren and his head was presented to the other blood elves.
