The SeaWing Royal Massacre is an event that occurred 2,005 years before the events of the main series. During the massacre, at least 9 members of the royal family (not including guards) were killed by Albatross, the royal animus, before a dragon (revealed during Darkstalker to be Indigo and Fathom's combined efforts, instead of just Indigo as written by history) killed him with a spear. The event led to animus magic being banned from the Kingdom, leading to Fathom swearing an oath with his sister, the newly appointed Queen Pearl, never to use his magic (which he broke once to defeat Darkstalker), and never to have children, so as not to pass on the animus powers (Also broken).
