Maw of Luukos
The Maw of Luukos is a valence near to Elanthia that is under the sway of the Arkati Luukos. It appears to mortal eyes as an endless expanse of green flame, called Mawfire, which produces incredible heat only when it comes into contact with living tissue. Stone and other non-organic materials seem entirely unaffected by Mawfire.
The souls of the dead naturally pass through the Ebon Gate to dwell with Gosaena for the remainder of eternity. Those marked by Luukos travel instead to the Maw, which serves as prison, torture, and holding pen until they can be sent back out to animate the undead as needed.
The Maw manifests in Elanthia at several locations. A majority of these are artificial and temporary, such as the breach beneath the city of Solhaven and one safeguarded by a group of trolls on the island of Glaoveln, but there are rumored natural breaches as well.
