King of Sisafir. A senate of wealthy nobles advise the king, one of which is Bartholomew's father. Has a mysterious connection to the Adamantine Soul. Killed by the party at the direction of Elisef's father Beneford after Kalosis ordered the city's clergy to be executed.

The late King Kalosis was the leader of Sisafir and was hosting the Deonar Summit in Kaladel during the party's first session. The proceedings were interrupted when King Hunan was assassinated atop his elephant palanquin in the streets.
 
Later on in the campaign, Kalosis gives an order which seems insane to his guard captain, Beneford Ironfist. Kalosis decrees all religious clergy in Kaladel's Belt of the Gods must be executed. Beneford asks the party to put an end to this madness by taking out the Adamantine Soul guarding the king, then end his life.
