Shard

A shard, or arc, is a series of three colors in an unbroken chain on the color pie. The middle color in a shard is its primary color, allied to both of the shard's other colors. In contrast, a combination of a color and its two enemy colors is called a wedge. 
==Description==
Prior to the official naming, Invasion block was the first multicolored set with some three-colored themes. Invasion and Planeshift were headlined by shard-colored Dragons as a reward for stretching the allied-color drafting. There were three cycles using 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 were not designed or marketed as faction names, so those designations fell by the wayside.
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.
Fourteen years later, the next major Shard set was released in the Streets of New Capenna, where the factions are crime families ruled over by demons.
