Bio:
Hadrian Amaranth Sev is a person of another world that was accidentally been sent to Earthland by being push into a gate that was used for execution. He was a former lord back in the other world and was trying to find a way to go back home by travelling into the new world he's been sent to. He is immortal and there's a speculation that the reason he came to Earthland was no accident. He's been there the first time the Fairy Tail guild was established. He became the shadow protector of the guild and for a time, was a spymaster for the magic council. 
Nowadays, he's a travelling hermit.

Though he is immortal, he can still feel pain. There comes a time that he gave up on trying a way to go back home and tried different methods to kill himself but to no avail, he still can't die. He was saved to his depression by the founder of the Fairy Tail guild, Mavis. 

Even though he's immortal, his body is still human that's why he suffers from the ailment of forgetfulness.
One thing is clear though, his fairy tail mark on his chest helps him remember and never forget to protect the Fairy Tail Guild from the shadows.
