I like how the last Kevekii clan's symbol looks like a little house.
Those are Avelūāvūālkūāl, literally "Defenders of Home", as they protect the homelands.
Happy that you saw the house there
Building on that, I'm guessing we have Forest (or if it's a trident it could be Sea?) Frogs, Mountain Frogs, Hill Frogs, Plain Frogs, and Home Frogs.
Is not that much tied to terrain or land. The first one is Waalwaurkūāl, their symbol is hand used and they live by the sea, but often send brave souls to the northern border to fend off giants. The second are the most toad like, Vokawalkūāl, Vokawak means stone or rock (their patriarch and founder, Havokawak literally translates to Like-a-rock). The third one, Kauvedalkūāl, lives in between these two and their symbol is eye. The fourth is Ejiiikyvolkūāl, their are the smallest and most tree-frog like. Their symbol, the straight line represents a path, a journey. And the last are homefrogs.
Ejiiikyvolkūāl and Waalwaurkūāl have smooth skin, the others have rough, with lumps and warts, to various extent. Of course Kevekii marry into other clans than their own, so not all of these physical traits are shared between all clan members, but they are fairly common within the respective population. Also the order they are drawn there does not mirror the order they were chronologically founded, they weren't established at the same time.
Enough talking, here's a picture!
