Killigan

Killigan is the aide of mayor Aidon of Britain at the time of Ultima IX.

When the Avatar first met Killigan, it became clear very fast that he was a really unpleasant man who seemed to agree on the mayor's fatal policy of deporting the sick and poor out of innermost agreement and not corruption. Later he proved his ruthlessness by having the mayor's own daughter, Maribeth, being deported to Paws.

After Aidon changed his politics, Killigan did everything to sabotage his effords. So when Kimberly in the Cathedral of Love complained that Killigan hadn't returned the cathedral's money to them, he/she investigated. With magic-aided vision the Avatar discovered a letter that proved that Killigan was actually working for Blackthorn. Killigan caved in when confronted with it, but right then the Guardian killed him for his failure.

Trivia

 * It's a well known plot hole that the Avatar can't tell Aidon of Killigan's treachery.
