Ranquin

Ranquin was the leader of the Swampies on Delta III. They turned to him after their forced exile from Delta Magna. He firmly believed that Kroll was a god, and worshipped him as so. In this respect he was also the religious leader of the Swampies.

In the Swamps
Some Humans began refining various elements on Delta III. They had not known of there deposits when the Swampies were transferred there. Ranquin wanted to attack the refinery as they were oppressed by the workers and forced into the swamps. They worshipped Kroll as Ranquin proclaimed him to be their god.

Against the refinery
Ranquin purchased guns from Rohm-Dutt for an attack on the methane refinery. The guns turned out to be duds; Rohm-Dutt was working for the refinery. He ordered the sacrifice of Rohm-Dutt, the Doctor and Romana to please Kroll. However they escaped, they Swampies chased them but Kroll appeared and attacked them. This made many Swampies doubt that Kroll as their god; Ranquin was firm in his belief, deciding that it was a test of faith.

He led a raid on the refinery and tried to contact Kroll who was also attacking. A tentacle of Kroll burst through a pipe and Ranquin approached it. Kroll then grabbed Ranquin and killed him. (DW: The Power of Kroll)
