Hmm they're different from what I have in mind. Maybe we could have related species?

It's possible, what were you thinking? Take into account that anything too closely related to them and their forest would be incapable of leaving without the assistance of the harkti leaves, and even then it's only as long as they have them. Anything too far from them would also be affected by the ecosystem in the same way as it would affect most other creatures from outside the forest, in that it would be a very unpleasant death.
