What is Allia?

Allia is the village to which Alabaster and Syen were sent on a mission. They were told they were to clear the harbor of coral, but the mission turned out to be more difficult. While in Allia, Syen and Alabaster were treated rudely by the government leaders. Someone attempted to kill Alabaster by poisoning him. Later, another Guardian tried again to kill Alabaster. Syen stopped the attempt by destroying the obelisk and creating a volcano. She and Alabaster were saved from the ruin by a stone eater.
