Dreadlord Gemeshet

Compelled by the scent of undefining in the Spaces, the Dreadlord Gemeshet has been drawn from the event horizon of the Nothing, through the Void to the Skyworlds

The White Wasps are drawn to the Dread Lords when they leave the Void
With the activation of the Pale House relic gate to the world, the White Wasps are being drawn to the portal quickly as is incredibly close to both the porous corrupted former Loxodon homeworld deep beneath the Skyworld clouds and the presence of the Nothing in the animated form of the Dread Lord Gemeshet
Gemeshet has whispered promises of death to the enemies of Zephyrus to a now cult of secret cabalists who have enabled it to emerge into the places

Like all other Dread Lords, Gemeshet is reacting violently to being outside of the Void, meaning it:

Risks becoming unstable very quickly
Suffers great agony; and
Seeks to incinerate its immediate surrounds to reduce it's suffering, using the White Wasps, Dread and unwittingly the Argent cabalists
