Vicious six-legged
weasel-like creature with fur made of actual gold. Beware! It's a high-level
monster and is a lot more vicious than it looks, although it's a great find for AD&D players more interested in treasure hoarding than adventuring.
"aurum" sounds like a Latin word
root and is adapted from the Latin word for gold. "vorax" is probably just invented (though again it has a definite Latin sound).
