Alexander "Alex" of Tirragen (pronounced TIHR-ah-genn) was a Knight of Tortall during the first half of the fifth century of the Human Era. He went through page training around the same time as Alanna of Trebond and was part of her circle of friends. He was a skilled mathematician and fencer. Duke Roger of Conté chose Alex for this personal squire, distancing Alex from his friends. Alex drifted away and became part of the Conté Duke's plot against the Crown. He was killed by Alanna in single combat during the Coronation Day Battle in 439 HE.
