Absolutely loved the update. I'd say you nailed the feeling of branched paths that Secret Histories can give, and it... well, it really felt like a branching tree, and it's fruits was sweet indeed.
Now, I since mechanically they'll be similar, the choice is more stylistic, or perhaps
What is the defining characteristic of Lizardmen? What would we want them to embody further?
[X] Tlazcotl - Old One of Will and Inevitability
Their unbreakable will and uncorruptible souls are seen nowhere else in reality.
They oppose Chaos and chaos not even by grand works they erect, but by simple fact of their continued existence.
It's quite inspiring, honestly.
[X] Xhotl - Old One of Fate and Choice
They are the closest to their makers, most aligned with their mission.
It is only natural that their fate is the strongest, as it's guided by the hand of the Oldest creators.
And it's quite heartwarming, honestly.
[X] Potec - Old One of Serenity and Protection
The world is filled with noise, violence, chaos, Chaos and plain disorder. Where everyone is at everyone's throats, where despair and desperation is everpresent.
Not for Lizardmen, however. Like a stone in middle of an ocean, the waves crash upon them, and they stand unmoving, unbothered. Still, quiet and serene.
And it's quite soothing, honestly.
