As a rule I never tell people what is going to happen in the story. I want you to read the comic to find out! Also, I like to keep things loose until I actually commit by putting it into a page.
But I do consider the green and orange cobra to be Rhea's actual snake design. You know, IF she were able to get a handle on it. And nothing is stopping me and my friends (and perhaps artists I commission) from having some fun with that!
There are people who have been cursed by Guardians like Kieri and Kazai have been. But anthropomorphic wolves like Kieri is in this picture would end up confusing people due to their visual similarity to Demons. People still often think that Tsavo is a dragon even though there are only 4 types of dragons in Slightly Damned (fire, water, earth, and wind-- except wind is represented by a variety of wyverns). So something like this is purely for noncanonical fun.
I don't think Demons do any sort of formal ceremony. In my mind, the Tamis triad are essentially married, but they haven't really made it "official". At least for now...
The following is 100% the truth: I have always liked Skarmory and I have had several over the years named "Tsavo" because that became one of my go-to nicknames for Pokemon while playing through each game. So I think this is very apt! And besides that, the art is really nice! It's surprising how well the asexual pride flag palette works for a Skarmory.
The Djinn are all a lot of fun! I once did a picture of every single one of them from Dark Dawn, a game in which each Djinn has a different design even with the four elemental types. I think Golden Sun was the point at which I started thinking earth magic was cool.
ANYWAY this is a really cute Venus djinn! I think they're my favorite.
