The Order of Summoners, one of the three Grisha orders. Etherealki manipulate natural forces and wear blue kefta. They include Squallers (who control wind and weather), Inferni (who manipulate combustible gases to create and direct flame - they cannot create fire from nothing), and Tidemakers (who control water). Rare Etherealki with unique abilities occasionally appear, such as the Sun Summoner who can manipulate light.
