I don't honestly know how I started thinking about this, but here I am.

There are 7 tribes of Pyrrhia, right? So, there are also 7 deadly sins.
So, you can probably see were I'm going with this because your a smarty pants.

Which tribe would represent which sin?

I think Rainwings would be Envy, either making others feel it because of their scales or vice versa.

Nightwings, maybe Greed? They wanted to kill off the Rainwings for their territory.

Gluttony could be Mudwings. I think their the only ones who eat big stuff, and Clay at least wanted to eat a ton.

Pride could be Skywings. Idk, I'm starting to second guess myself.

Wrath fits Sandwings, being the ones who started the war.

Alright, the ones left are:
Lust and Sloth

And the last two are:
Seawings and Icewings.

What's your thoughts on this pointless topic?

Probably: "Your an idiot, Voss."
