Much like how christianity has the cross and judaism has star of david, Axolotlism has a symbol, a 5 pointed star in an 8 pointed star.
The 5 pointed star is the 5 alive gods, and the 8 pointed star is the total 8 gods.
Coincidentally Axolotlia has 8 Scires, and some theorize that when the Scires were being redrawn at independence, they were specifically made to 8 for the gods, but no. It is a coincidence, 8 was a more stable setup with no needlessly small Scires.
