what is his name and where is his backstory?

[Shimesen]

im trying to find the name and backstory for the iconic magus from all the books, but i cant find anything on him so far. all i know is that he's a half-elf magus and in the mythic book he looks awesome with his shirt off...

anyone know where to look for this info?

He's also LE and a worshiper of Asmodeus. As is noted in several stat-blocks of his, along with high Str and Int. Everything else varies a bit.
