Pretty much! How they’re dispersed is a mystery as a Yehk will brood over her nest for a while before they’re somehow scattered among Kurosia. Wether they themselves spread them is unclear but it’s more likely it picks out which will be a Yehk egg (as they’re twice the size of normal eggs and a single clutch of 50 will produce one Yehk bab).
Though since Malefor made the Gods fall asleep (except for a few), they haven’t been able to give birth to the Olfur’Yehkshir (who give birth to the smaller normal ones). Slowly, the Black Swords are wiping them out~
