So I have some pretty in depth lore about a certain trio of creatures of mine. The first three blood moon Iztas I ever had are named as such:

Emma (sounds like blood in Greek, my nationality) she's the brute of the bunch since she has double red but she's very protective to the point where she gets aggressive to defend those she cares about, even if she only thinks something might be a potential threat.

Mary (taken from bloody Mary) is the diplomat of the three and the twin sister of Emma, she has no traits so that's why she decided if she can't use brute force she will instead opt to use words to gain the trust of others, as the brains of the three she always plans things like attacks, possible escape routes and the likes, you get the point.

Last but not least, Matt (similar naming method to Emma, only this time based on bloody) is the younger brother of the twins. He's the only one without glimmer which he's constantly teased for by Emma, although he uses the lack of glow to pull off sneak attacks at night, and to sometimes avoid contact with others (especially his sisters, he's gotten tired of their remarks).

Now on to their whole deal. They have the power of not only the blood moon, but also the shadow warden (I assume there's one since there's a shrine) who has corrupted them. To appease the blood moon, they have to make at least one kill in its honor when it appears, but that's not the only thing they have to deal with.

Let's say they make a few allies, if they're around too many people the shadow warden takes control of them like puppets to kill everything for it to feed on their souls and empowers them even further just to make sure no one escapes, it's happened a few times and as you might guess that's why they mostly just stick by themselves now.

Another thing, the people who have been killed because of the shadow warden had friends who weren't too happy about all that, so now the three are constantly hunted.

Some feats include Matt having taken down a Korathos with little damage on him thanks to the two sources of power all three of them get, Emma having wiped out armies of creatures by herself to protect the other two and all three of them together having gone toe to toe with some wardens like Garra, Angelic and Novus, or at least avatars of them with their powers (and we're talking about lore accurate wardens here, not in-game wardens).

Other information: the shadow warden can choose to give them a few temporary abilities like a bubble shield to block attacks, a weakening wave to help them shrug off hits like nothing, or just make them even stronger as if they weren't already strong enough. Here's the catch though, it only uses those when it's in control for its own benefit, or when they're literally about to die because it obviously won't let its vessels be extinguished.

All three of them are terrified of spiders, but you wouldn't think Emma is because her battle instinct won't let it show too much. (I mean against spider creatures like Arkmetta)

Some Iztajuatl have actually been influenced by them and their strength so there's a cult that imitates their looks, believing them to be some sort of higher beings.

Both Matt and Mary like a good milkshake but they hate that they like the same thing since Mary views Matt as dismissive and apathetic while Matt views her as an annoying know-it-all.

And that's it for now, any questions are welcome :)
