Because these new Marid States are located in deep water beneath the Hmur Plateau, their residents face no direct retribution from the elves for their expansionist activities. »

They establish three crystal-doomed, subsea colonies - Cuulmath, Werapan, and Quelauuvis - on the continental shelf off the land that will become Sembia (over the Plains of Duna), which is within claimed territories of the elves and merfolk.

Foreces at the siege noted only a strange humming rising from the mythal and numerous discharges of magical energy lightning the night-darkened sea. When the forces swam into the city, they found the only person alive was the sea elf Dukar Yupal Narlis, his mind destroyed. His thirty Dukar followers and "nobility" stood along the avenue leading to the Council Acadamy of the Dukars, all transformed into coral statues with looks of contrition on thier faces. »
