According to research from the Ivory Tower, the established theory is that Kamaloka is from a dimensional overlapping in Aden's land. Kamaloka has stages of power based on the strength of a monster's soul. This is cutting edge science, and we don't fully understand it. So we introduce adventurers to Kamaloka that's appropriate for them.
Levels of Kamaloka notified by each captain are as follows.
Captain Bathis (Town of Gludio): levels 23, 26, 29
