The Dragonrise

The Dragonrise was a rebellion against the dragon overlords of Ishtoc. This rebellion was sparked when metallic dragons attacked the chromatic dragons of Ishtoc in 1170 CE. Chromatic dragons, dwarves, lizardfolk, kobolds, humans, elves, dragonborn, metallic dragons, and halflings were involved.

The rebels came out victorious. The rebels' carpet bombing magic usage resulted in mass casualties on both sides. Overuse of magic also caused magic to become unstable and wild. All dragons fled or were killed by 1200 CE. The Ishtocian deserts became glass, but over time the glass was covered by sand. The glass is rumored to have magical properties because of what caused it.
