Fact is, we have one recorded influx of Praxians, along with their beasts and presumably their myths, into Dara Happa, as it happens just before Mr Plentonius wrote his book. Lots of Bison and Sable people remained after Argentium Thriile and settled in the River Valley. Possibly also Impala people, if so, their traces have been obscured or just not yet reported; High Llamas or Morokanth don't seem to have participated.
The immigrating Praxian nomads simply took over the role of the horse-riding warlords who ruled that part of Peloria since the Dawn. They swore allegiance to the Dara Happan Emperor; how firmly they kept it may have varied.
Fact is that they became a fixture in Dara Happan nobility, and have remained there since. By now (1621) they are Yelmites, have been so for generations, and apart from strange aspects in their ancestor-worship, involving strange beasts, are model Dara Happan patriarchs.
If they could adopt Dara Happan myth that completely, couldn't they have slipped in facets of Praxian myth into official Dara Happan theology? Especially since this was collected and fixed when they were present?
