Djo,
Long, long ago, in a galaxy far, far away... shrouded in the mists of time... once upon a time?
A contextual analysis of
my turn 0 shows that Aetonyx was long dead as of five generations of lizards ago. But lizards grow up fast, and can have rather short generations. How short, I'm flexible on... perhaps this ancient war was only a few hundred years ago. Myths can be so unreliable for accurate dating.
The real point, of course, is that it completely and utterly explains why Jontunheim has never been in any Yarnspinners game up 'til now. 'Cause the lizards killed them off.
