From the 'What the heck is this' files

Over on the right it says I am a relative newcomer to the Warhammer world - but that's not entirely true.  Back when I was a kid I dabbled in both Warhammer 40,000 and Warhammer fantasy.  Back then I had nobody to play with - none of my friends were the least bit interested, and the web - not having been invented - meant I didn't have an easy way to meet up with like minded individuals.  All this meant that my initial foray into the hobby was pretty much relegated to painting the small number of models I could afford and setting up small dioramas in my bedroom.

As a result I have a small number of models from my childhood that are either unpainted or painted badly.  The majority of these models, however, are no longer available.  Some I have been able to track down on the websites that list the Citadel/Games Workshop back catalogues.  A couple though have proved elusive to identify.  Once such model is this:

Glorius though he is - what, or who is he?

It's obviously some kind of chaos demon, and I'm assuming it's from a fantasy game, not 40k.  Definitely from Games Workshop circa 1993 as the tab at the bottom says (c) GW 1993 I think!

The front of the tab has some text which I believe is Rangor - but I've been unable to turn anything up by searching the web.

Rangor - I think!

If anyone has any further information I would love to hear it.
