Trivia

 * In the Bible, Abaddon is the name of an angel, who will rise from the Abyss and command an army of locusts. His name means "the Destroyer" in Hebrew.
 * Abaddon's title, Lord of Avernus, is a reference to the famous crater in Italy, which is believed to be the entrance to the underworld.
 * In DotA, Abaddon's third skill was originally called "Frostmourne." It had to be changed in transition to Dota 2 due to copyright reasons, since Frostmourne exists as a famed weapon in the Warcraft universe.
