Nearby (legend says) there's a colossal cave where others have found fortunes in treasure and gold. However, it is rumoured that some who enter are never seen again. It is also said that magic works in the cave.
Your goal is to enter the cave and bring all the treasures back to the nearby building.
This is a faithful reproduction of 'ADVENT' by William Crowther and Don Woods ported to Atari BASIC by Robert A. Howell.
It was originally published by Creative Computing in 1980, then by the author himself in 1982. A third version has been reported as being published by Lotsabytes.

Could possibly be a duplicate entry for one of the early Scott Adams releases.
Oh, it's this game...
