Dragons

Dragons are huge, flying, fire-breathing reptiles with a strong mind and fearsome magical abilities like the ability to summon Daemons and becoming invisible. Only a fool or the strongest warriors would challenge a Dragon to a fight. But such perils are usually rewarded with the treasure the Dragon kept. Dragons can come in quite a number of variety. The Dragons of Britannia usually are either green or red in color, while the rare Ice Dragons of the Serpent Isle are blue in color. Ice Dragons mate for life and sing to each other during courting. Their blood can cure almost any disease.

Dragons can usually be found in dungeons, but they also roam the wilderness. The most well-known dwelling place of Dragons is the Dungeon Destard.

First seen in Ultima III, Dragons stayed a part of the series to the very end, with exception of the two Underworlds (for obvious reasons) and Ultima VIII. Due to the enormous difficulty that laid in defeating a Dragon, their power was reduced in Ultima VII, to give players a fair chance to defeat them. In Ultima IX, Dragons seemed to have lost all magical abilities and yet, at the same time, there seems to be three types. There are green, blue and red dragons, now. There are several of the green variety throughout the world but only two blue dragons (and you have to hunt to find them) and only one red dragon.

Lore
''Dragons are a mysterious ancient race of highly evolved reptiles that possess magical abilities and a high degree of intelligence. They have large wings and are capable of rapid flight. A dragon is formidable in combat and is all the more lethal due to its noxious flaming breath. Its lair is usually a cave or a dungeon where it guards its eggs and treasure.''

Named dragons

 * The Avatar meets Dracothraxus in the Test of Courage on the Isle of Fire in Ultima VII. She is one of the few Dragons that didn't attack the Avatar at once but instead talks first. Attempting to kill her is futile, since she is invincible. However, a won duel gives the Avatar possession of the Ether Gem, to forge the Black Sword, which in the end would be the key to destroying Dracothraxus.
 * Riddle-loving dragon Draxinar, also known as "Stumpy" due to his tendency to stump people with his riddles, appears in Ultima VII Part Two: The Silver Seed, in Aram-Dol's Lair.
 * Taloria is the only red dragon in Ultima IX. You need to kill her and take her head back to the Isle of Valoria in order to gain entrance to the volcano. She likes to talk to you first but, afterward is easy to kill.
