The [[devnull tournament]] includes a Grue Challenge that causes instadeath if the player attempts to do anything in a dark area without a light source. The [http://nethack.devnull.net/tournament/trophies.shtml trophy description] states, &amp;quot;harkening back to Zork, players accepting this Challenge must find and figure out how to use the Frobozz Company Inter-Dimensional Portal Generator before being eaten by a Grue&amp;quot;.&lt;br /&gt;
