First game

Fire Emblem Heroes

The SP Aether Stone (Japanese: 記念の飛空石 Memorial Sky Stone) is an item appearing exclusively in Fire Emblem Heroes. SP Aether Stones, added in the version 2.11.0 update, are the means of building and enhancing special event-based structures of a player's Aether Keep, and one of three items overall that allow building a keep, the others being the Aether Stone and Heavenly Dew.

SP Aether Stones are primarily won via quests during periods where special event-based structures are made available, and vanish from a player's inventory upon the event's end; these quests distribute enough SP Aether Stones to build all of the event's special structures. There are five different forms of SP Aether Stone, four of which are themed to seasons of the year: the standard SP Aether Stone, the winter-themed Frosty Aether Stone, the Spring Aether Stone, the Summer Aether Stone, and the Fall Aether Stone.
