People of the Taldur
A race of humans making up several island states under the banner of the Taldur, a judicial body who lay down the strict law of the land. The people of the Taldur were once assaulted by the presence of Linea
, called "Destroyer of Worlds," who created a sickness that destroyed half the population. She was, consequently, banished to the prison world Hadante.
The people under the jurisdiction of the Taldur live under constant fear of disobedience, and its penalty.
