 * The Amulet of Aurora-Hippogriff artifact; as revealed in The End in Friend, it can "reverse the tides and summon tsunamis".
 * Clover the Clever's Cloak-Pony artifact, qualities unknown.
 * The Crown of Grover-Griffon artifact, qualities unknown; was used by Grover to become the first king of Griffonstone.
 * The Helmet of Yksler-Yak artifact, qualities unknown; Yksler was apparently such a presence that his enemies would lay down their weapons instead of fighting, though whether the helmet had anything to do with it has yet to be established.
 * Knuckerbocker's Shell-Dragon artifact; can be blown into in order to call a dragon; possibly based on or intended to be the summoning shell from Daring Do and the Eternal Flower.
 * The Talisman of Mirage-Changeling artifact, qualities unknown.
