Destard

The dragon caves of Dungeon Destard, situated in the mountains west of Trinsic, are a very dangerous place. Many of the dragons and drakes of Britannia call the warm caves of Destard their home and breeding place, and they react extremely violently to intruders into their home. This usually results in the quick destruction of the intruders by their fiery breath and powerful magic. Many adventurers have entered Destard in pure greed, only to regret it after meeting its inhabitants. Their remains still bear silent witness to their lust for gold.

Because of its inhabitants, Destard can only be mastered by expert adventurers with very good equipment. However, should the dragons be overcome, a huge treasure awaits their bravery.

Ultima IV
Destard was first entered in Ultima IV. The Red Stone was found in there, and a magic orb that gave one experience boost. Destard connected to one of the Altar Rooms. It was a natural cave system filled with nasties. After the end of the Quest of the Avatar, the Great Council sealed the dungeon, to lock the horrors within.

Ultima V
New monsters were settled in the dungeon in Ultima V, when the Avatar visited Destard again. The Avatar yelled the Word of Power "INOPIA", learned from Goeth, to open the entrance. It connected to the Underworld, where Lord British's Amulet was found.

Ultima IX
Destard hasn't changed much. It is still a dragon cave; although, Talornia is the only dragon present. The over half of the dungeon is home to the Wyrmguard, including Dartane and Yerffoeg, who mine the rich minerals of the dungeon using slaves, including Bane, in return for dragon eggs from Talornia. Before the Avatar's arrival, Talornia had attacked the city of Dawn, and half the population wanted to appease the dragon while the other half wanted to fight. Those who wished to fight betrayed and all were killed, including Adreanna.

Destard is also home to a cult whom worships Talornia, led by the priestess Saphera.
