A subterranean creature, famed for its voracious appetite, its loathing of
sunlight, and its primary dietary staple, adventurers, enchanters, and (you
guessed it) hitchhikers. No one has ever successfully captured the likeness
of a grue although tales of near escape from their ravenous jaws filled with
razor-sharp fangs are not uncommon. They are considered quite evil,
although none are known to be aligned with any exact incarnation or
manifestation of Evil, and are best avoided.
NOTE: Grues are mentioned in the Zork myth-cycle (see Zork).
If you think you're in the vicinity of a grue, here are a few questions
to ask yourself:
1) Is your immediate locale medievalish or fantastical? Would
you describe any of your companions as trolls, ogres, or little
Hobbity-things?
If the answer is no, you have nothing to worry about. Grues
(or the rumored existence of grues) have been documented only
on planes of reality which are decided Tolkienesque -- dusty,
moldy, dark ages.
If yes, move on to question #2.
2) Are you in the complete, impenetrable dark?
If the answer is no, again, you're okay. Grues detest even
the slightest ambient solar light.
If the answer is yes, we can offer but one small bit of advice,
although it generally goes against the editorial policy of the
Guide:
Panic, for Zarquon's sake!
