Aeon made his
first appearance in Castlevania: Judgment and was designed exclusively
for the game. Aeon is a member of a group that watches over
and preserves the flow of time. It is because of Galamoth seeking to take Dracula's
throne by erasing the time that he lives in, Aeon goes into action to correct
the disturbance to the flow of time by gathering the 13 soul keys and using
them to find a chosen warrior to stop Galamoth's messenger, The Time Reaper.
