They are memories of previous host bodies.
all the same joined being though.
Indeedy, it's just the Kheldian's master of energy manipulation letting them transform into an energy based duplicate of a previous host.

Thanks guys. Makes sense now.
When I'm RPing I don't know if I should count the dwarf form and the nova form as the same kheldian. Or are they two different khelds in the same body as my character? I want to RP close to the canon of the Kheldian lore, but I don't know how to RP this.
