Malkizid...whozzat now?

[Alzrius]

I was glancing back through my copy of the Player's Guide to Faerun again, and noticed something that I'd been wondering about for a while now. The "Archfiends and Paragons" section on page 189 talks about several demon princes, and two devil princes. One of the devil princes is named Malkizid. I've been completely unable to find out who that is. Every search I've done has come up blank. If anyone knows who this guy is, and where he's referenced, please let me know!

I think that I read in a designer interview that there were supposed to be a few new archfiends in the book.

Ah, here it is: Link

Wizards: Were there things you'd hoped to include that just didn't make the cut?
​

James: Lots of good stuff got squeezed out, like some new archfiends, but we're trying to find a home for all the orphaned material.
​

Most likely this Malkizid is one of them.
