Covetous

Covetous is a dungeon south of Minoc and for much of its history its only surface access was via Lost Hope Bay. One of the eight famed dungeons of Britannia it first appeared in Ultima IV and appeared in every Ultima that took place in Britannia afterwards.

Ultima IV
The Anti-Sacrifice Dungeon of Covetous was first entered in Ultima IV where ferocious orcs and savage trolls made it dungeon their home. The Orange Stone was found in it, and magic orbs which increased dexterity and strength. The dungeon connected to two of the altar rooms.

Ultima V
Hewn long ago as a royal crypt for the rulers of a distant province that is now Minoc. After the end of the Quest of the Avatar, the Great Council sealed the dungeon, to lock in the horrors in it. In Ultima V, Covetous again was visited. The Avatar yelled the Word of Power "AVIDUS", learned from Fiona, to open the entrance. It connected to the Underworld, where the Shard of Falsehood was found.

Ultima VI
In Ultima VI, the dungeon was a series of cells, holding all manner of beasts, which now joined with the dungeon Wrong. In it the Avatar found the Heftimus McPry's scrap of Treasure Map.

Ultima VII
20 years before Ultima VII, the Britannian Mining Company destroyed the entire upper level of Covetous in their mining operation, after unsealing it and destroying all monsters on that level, where also blackrock was found.

Ultima IX
Covetous is a complete mine in Ultima IX. All levels contain blackrock and gems. Being abandoned, the mine's lowest level has filled with water.

Trivia

 * In Ultima V, the seventh level can only be entered from the sixth via the spell Des Por. There are two ladders on the seventh level going up. Each leads to a room; one which has a one way only exit back to a room on the sixth, the other having no exits.
 * In Ultima V, Covetous, as the name might suggest, is an excellent place to farm for gold. On the first two levels half the rooms respawn (including a high end weapon and shield per room), there are no pits or traps, and there are healing springs easily available.
 * In Ultima VII, Malloy and Owings can be found in Covetous.
