We were created by the Bestower, and placed on the world to rid it of its native life, unpleasing to Him.
He gave us the living Bestowed to sustain us and replace what was there before. Thus say the priests, but now that myth is questioned: Native life has evolved; why not ourselves and the Bestowed that came with us?
Are not all native, and necessary for survival? The evidence is contentious: Exterminate, or conserve?
There is increasing dissension and the threat of war.
