Prior to the official naming, Invasion block was the first multicoloured set with some three-coloured themes. Invasion and Planeshift were headlined by shard-colored Dragons as a reward for stretching the allied-colour drafting. There were three cycles with the dragon's names, with four other cycles with [word]-Scape (Sun, Storm, Night, Thunder and Thorn) as a name for the shards. These names did not stick, and three-colour spells were not developed further for many years.
The official term "shards" was established in the 2008 expansion Shards of Alara. It depicts the plane of Alara divided into five shards, each having only three of the five colors of mana. Each shard has its own flavor and gameplay mechanic related to its place in the color pie.
