What would be the third psionics class (and the fourth, and so on)

We have 2 psionics classes in draw steel right now. The talent, and the null. i describe those two classes (to my friends usually) as someone who uses psionics, the power of the mind, to manipulate their surroundings; and someone who uses psionics, the power of their mind, to enhance their body.

i feel like the contrast between the talent and the null is very cool, they feel perfect. Which brings me to my question. If you are given a chance, an opportunity, to design the third (and fourth, and so on) psionics classes, what would they be? what would they do? what makes them different from the talent and the null? what kind of fantasy inspired those?

i can imagine if today James Introcaso calls me and be like "Hey Laz! Pitch me a psionics draw steel class right now", i would be like "Hey James. i thought you're not working on draw steel anymore 🤔", I'd then be pretty stoked and afraid that James knows my number, and then I'd be stuck thinking about what the 3rd psionics class would be and what kind of class and fantasy I'd want to pitch. Because the talent-null dichotomy looks and feels like a perfect psionics duo already.

maybe a kit-class with psionics? kinda like the battlemind kit, but more fleshed out? maybe someone the "flying sword" archetype? like you know, someone who can manipulate and use melee weaponry remotely because, telekinesis, somehow. But then you'd run into the subclasses, and making 3 subclasses for this feels very hard. but idk. what do you think?
