I cannot escape this burden

Ambition (Rella)

Ambition placed a planet (in the image of Yolen) between what would become SEL and the sun. The planet is dangerously close to the sun, and would kill surface-dwellers. However, Ambition place a dust storm with aluminum content, permanently surrounding the surface.

.Below the surface, there is an interconnected system of caverns, where life is, in reality.

The life comes as carnivorous plants and predators. The plants would try to (and succeed in) growing quickly, fighting to deprive each other of resources and kill each other off.

Yes. Um.

Words. 

Predators endure a competitive environment, the strongest only growing stronger as they fight - not for food, but for access to the rivers of Rellium, molten metal which does in fact hurt them. However, it empowers them, as well as the plants.

So you have predators, what about the prey?

Also I don’t think this ecosystem would be healthy if all the plants are carnivorous.
