Strata

All magic, be it spells or songs, is divided into seven strata. These are different layers of magic which lie beneath every day reality. Any user of magic can access any of the layers; which one is used for a particular spell is a matter of convenience and is inherent in the spell. The seven strata are:

Stratum	Color	Shard	Zones
Channelling	red	metallic crystal shard	Orc Mines [IS] Sky Elves [SS]
Shaping	orange	veined crystal shard	Centaurs' Domain [SS] Earth Plane [AH]
Summoning	yellow	luminous crystal shard	Deemonee Warren [IS]
