Tomb of Kings (UO)

In the Ter Mur of Ultima Online, the Tomb of Kings is the final resting place of the kings of the gargoyles. It also houses the entrance to the Stygian Abyss.

Entering it, one first has to pass the magic walls, saying "Ord" to the Flame of Order and "Anord" to the Flame of Chaos. Walking through the tomb next, one has to be aware ofNiporailem the cursed Gargoyle thief, who'll try to bury intruders under piles of fool's gold.

One final barrier are the guardians, who'll only let people pass who have a sacred quest from the Shrine of Singularity.

Trivia

 * The Tomb of Kings of course also is a place that does exist in Ultima VI, that map in Ultima Online even looks a lot like the original one.
