Thank you so much for moving your thessyx questions so that we didn't miss them!

The thessyx don't understand how the hatching works — they only sensed it happen. However, they seem to strongly believe that it was the leviathan's doing and that it reflects that the Children of the Leviathan are somehow 'chosen' by it. For what, they can't say.

As for the critters, the thessyx seem to view them as a natural part of life on Ethyraia. In this as in all things, they advise finding a way to cohabitate with the climate.
