The Skylands Runes are a collection of recurring symbols seen in the Skylanders franchise. Though they are not the only symbols used, they frequently appear as decoration or empowering artifacts in many objects throught Skylands.
In Skylanders: Universe, they were used as a language, with which the codes that Skylanders figures game with were "translated" to be summoned into the game; but in other entries they appear to have no literal meaning as no phrase written with them corresponds to the "language" used in that game. The Shattering Sigil is a notable artifact using a rune, and most Portals of Power feature several of those symbols engraved on them. The Runic Headband hat, first appearing on Skylanders: Swap Force, is a floating circlet made of these runes.
In Skylanders Academy, Skylands Runes are also used as a written language, though the regular English alphabet is seen more commonly.
Rune appearances are in chronological order by the games and/or other media's release dates. Examples which apply to all games, such as hats, must be put on the main heading.
Runes are featured prominently in Time Town and by extension the Clock Rock, though oddly only the inner clock of the main tower has them replacing the numbers, while the four outer clocks have nothing.
The sword conjured by the Darkness for Kaos' battle at the Sky Eater had the runes at each of its sides, and the corresponding runes appear on the ground as a tell-tale sign for where it would hit next.
