- "It is pitch black. You are likely to be eaten by a grue."
- —Zork I
They are famous for their horrible fear of light: No grues have ever been seen by the light of day, and only a few have been observed in their underground lairs. Of those who have seen grues, few ever survived to tell the tale. Grues have sharp claws and fangs, and an uncontrollable tendency to slaver and gurgle. They are certainly the most evil-tempered of all creatures; to say they are touchy is a dangerous understatement. "Sour as a grue" is a common expression, even among themselves.
In former days it was believed that all grues were eradicated from the face of the world during the time of Entharion the Wise, many by his own hand, and his legendary blade Grueslayer. Nonetheless old hags used to scary little children by telling them that grues lurked in bottomless pits of the Empire.
It is now known that uncountable hordes of grues escaped the blade of Entharion until they were accidentally released in 883 GUE by a peasant who would eventually become the First Dungeon Master. At this time the grues quickly spread to every part of the Great Underground Empire, including passages underneath Festeron, Antharia. It is there that a Festeron postal worker stumbled into the nesting place of a family of grues. A close call on the part of this postal worker demonstrated that only the mother-instincts of a female grue are strong enough to overcome a grue's fear of light.
Grues play a minor role in the tale of the demon Jeearr. During his control of the area surrounding Egreth Castle, Jeearr was using infernal machines to breed mutated grues that were not afraid of light. Luckily for mankind, these grues were never released into the world at large.
An interesting historical footnote concerning grues is the fact that one grue lair was, for many eons, the resting place of one of the Cubes of Foundation. In order to recover this cube, in 966 GUE the Head of the Circle of Enchanters was forced to temporarily turn himself into a grue as a part of a quest that would eventually result in the end of the Age of Magic.
Appearances in Infocom gamesEdit

The phrase "You are likely to be eaten by a grue" is used in Starcross.
