Aidan has spiky, silver hair, dark grey eyes and fair skin.
Aidan's attire consists of a green coat over a red shirt and trousers, and blue shoes.
He is referred to as "the eternal darkness" by some of the tablets within the castle.
He later makes his first physical appearance in the Top Floor Throne Room, where he battles against Serenity Horton. Serenity manages to defeat him, though briefly - he and his fiancée Tranquility pilot the Death Orb Mk. II. After another long battle, Serenity emerges victorious.
- Aidan is the final boss, but a true final boss has been confirmed.
- Despite being a driving force in both Lunar Shadow mods, he's currently only fought in Lunar Shadow (and not its prequel).
- He is based off an actual person, in this case it's Alexis's real brother who was victim to an impersonator. This same impersonator created a mod known as Shane's Cave Story.
- His family's surname is the name of a one-handed sword (with a curvy patterned blade).
