Lord Blackthorn

Lord Blackthorn is the central villain of Ultima V. He also makes an appearance in Ultima IX.

Blackthorn's real-life counterpart is Starr Long, one of the long-time Origin employees, best known as the co-creator of Ultima Online.

Blackthorn was, prior to Ultima V, a close friend of Lord British, and known as a very virtuous and wise man. So it came as no surprise that Blackthorn was chosen to rule by Lord British, while he would explore the Underworld. However, the Shadowlords, once they had captured Lord British, started to twist and poison his mind, and in the end, Blackthorn became cruel and evil.

He codified the Virtues into draconian laws, and erected a horrible dictatorship under the influence of the Shadowlords. This was the state of things in Ultima V, when the Avatar arrived. Blackthorn tried to imprison Lord British forever, as he also told the Avatar under the impression, that the Avatar had joined the Oppression (a lip-service done by the Avatar). But Lord British was freed, and the Shadowlords destroyed. Blackthorn, now free of their influence, became aware of what he had done, and accepted Lord British's offer of exile rather than face the judgement of the Great Council, whom he had persecuted or jailed during his rule.

Walking through a red Moongate created by Lord British's Orb of the Moons, he vanished from Britannia to an unknown location.

It is known from a book on Serpent Isle that he lived with the Xenkan Monks for an undefined span of time, becoming a humble man by their accounts. He left the monks to go on his own travel before the Avatar arrived on the Serpent Isle. What happened to him after this is not known.

In Ultima IX, Blackthorn returned to the Britannia as the Guardian's left hand. (Most fans found this turn of events extremely curious, considering how Blackthorn apparently left the Monk Isle as a better person!) His motivations are never explained in the story, though he appears to have an agenda of his own he is ultimately killed by Lord British in the Abyss.

Trivia

 * If you are captured in Castle Blackthorn without a Black Badge and the password of the Oppression, your party will face Blackthorn's torture chamber. It is possible for your party members to face permanent death here, though the Avatar him/herself is never killed.
 * Blackthorn held the Shield of Valor, before acting as the ruler in Lord British's absence. The shield is found in Ultima Underworld I.
 * Blackthorn is impossible to kill in combat in Ultima V.
 * Some fans, particularly those who ignore Ultima IX, believed Blackthorn to still reside on Monk Isle - and thought he was the nameless Xenkan monk who observes the salt tides. However usecode reveals that this Monk was named Bracchus and leaked design documents suggest that Blackthorn was meant to be one of the spirits to appears at Mortegro's home - hinting that he was meant to be dead at the time.
 * Ultima IX retcons Blackthorn's banishment as being to the Etheral Void instead of an unkown world.
