The Lorath are a caste-driven race meaning different societal tasks are broken down into sub-species of Lorath - each seemingly evolved to exceed at their given task. Note worthy is that while it is normal for siblings to copulate, cross-caste relations are seen as unusual and sometimes distasteful. Important is that there are always exceptions to the rules.
The Helashio - The former surface rulers of Lor who were reduced to a slave-class when the Lorath emerged from their underground dwellings out of mercy instead of wiping them out. Formerly, the Lorath were the slave-class of the Helashio.
