Fate of an eternal star

In a world I'm currently building, I've devised a magical creature that sustains, indefinitely, a Class O hypergiant star. This, of course, violates conservation of mass and conservation of energy.

Class O hypergiants tend to detonate in short order (in astronomical terms), but they produce the heaviest elements that occur naturally in the universe. If such a star could be sustained by my creature, what would happen to the star in the long term?

Would it continually smash together increasingly dense atoms to form an increasingly dense core? If this happened long enough, would the star collapse into a black hole?

Finally, what mechanism do I need to give my creature to prevent its presence from unintentionally destroying the star it preserves, if such a stellar fate is determined?
