DarkStar

The Cloud Castle that was grounded to near Dalzon, and which according to Bez Drock is now being either fought over or disputed between the Solarans and the Lizardmen.Zoom session 18th March – Meeting Bez Drock. Given the Elves had taken Dalzon, it is not clear what happened to them...

The remains of the city are known by the locals as The Dark Temple.
This may be referenced in Legend 26 - GARM: "you are but to reach for the stars and seek the star that is no light".
==From Legend 23 - Temple of the Dead:==
"The Dark Temple is a Cloud Castle built around the Guild of the same name."
Onwen's notes question why the Elves would have been involved with the Temple of the Dead, and why the city was grounded in the East rather than nearer Ghoulagabba.
