It threw me at first, the switch of Sedra to male, but it doesn't take away from the story, I am guessing it was unintentional? But it did get me thinking about pronouns, it's easier to work with a he and a she, yet you upped the challenge with all male characters, and still, every time you say he/his, I know exactly which one you mean. Well written!

You have equally gone for a full on action scene which isn't easy in 500 words, but it comes together so well, it's very enjoyable. There is a lot to be addressed and tied up in this first half, but I love the way you have the bracelet as a pair, it feels right, and just ties up so much.

The way Nox moves

Pukho tried to ram them again, but the skillful Nox fired his tongue at the branch of a nearby tree and rose in the air beside his rider.

It feels like you have captured the creature in the first half really well.

The beaked creature in the well, the feathered Pukho, there is a real sense of mystery, especially with the mist. It doesn't feel like Sedra knows its down there, and then the surge of power in her bracelet, it feels like The Well is a physical hole in the ground that might have once contained water, as well as being the source of their psionic powers. Just magical!
