As the tribe struggled with surviving, they had another issue. Many kits were born with deformities which made things much harder on the already struggling Tribe. In order to try and lower the deformities and mutations, and prevent them from being passed down, they would sacrifice the kits with any type of deformity - reguardless of how small - to their ancestors by drowning the kits and laying them down in a river for their ancestors to pick up and bring to the skies above. This was said to cure the kits of their deformities to be brought back later in life as a new healthy kit. Although there was no proof of that being the case, it was something they continued to do for a long time.
