Wrong

Dungeon Wrong is an old, long-abandoned prison complex—once the most feared in Britannia—located on the western shores of Lost Hope Bay. Where once guards watched over their prisoners, now reside various humanoid creatures: trolls, gremlins, headless, and others have made these walls their home, with rumors of liches also abound. The underground complex is riddled with locked gates and traps of all kinds, but also with lots of loot, witness of all the stuff the inhabitants have stolen.

Still, while complex, Wrong isn't too difficult of a dungeon, and a seasoned warrior should have no problem dealing with its denizens and looting the place of all its treasures. However in Ultima V level 8 seems to spawn a never ending flood of Daemons which is very dangerous.

Ultima IV
The Anti-Justice Dungeon of Wrong was first entered in Ultima IV. The Green Stone was found in it, and the magic orb in it gave good experience boosts and it connected to two of the Altar Rooms. It was, already back then a empty underground prison, given up after everything went wrong. After the end of the Quest of the Avatar, the Great Council sealed the dungeon, to lock in the horrors in it.

Ultima V
New monsters settled in the dungeon in Ultima V, when Wrong again was visited. The Avatar yelled the Word of Power "MALUM", learned from Felespar, to open the entrance. It connected to the Underworld, where the Shard of Falsehood was found.

Ultima VI
In Ultima VI, Heftimus McPry had lost his piece of the map in it, forcing the Avatar to retrieve it. Wrong during that time also connected to the dungeon Covetous.

Ultima VII
Wrong didn't change much after that. In Ultima VII, the Avatar visited the dungeon to loot it.

Ultima IX
Wrong is a regular prison in Ultima IX. Raven is falsely put there by the corrupted court in Yew. The Avatar enters through a secret back door with the aid of Vasagralem. Inside the prison the player can free Raven. The Avatar is able to use her key to reach the column and retrieve the Rune.

Trivia

 * In Ultima VII, Wrong actually consists of three parts.
 * In Runes of Virtue, the hero must delve into the Cavern of Injustice to retrieve the Rune of Justice. The hero could also meet the young bard Ariana and the gypsy Zoltan within its depths.  A magic boomerang and a mystical set of panpipes could also be found within the dungeon.
