Even though it was a Sacred Artifact, it was currently facing a Sacred Flame of equal standing. Given its heavily damaged state, it had no confidence in being able to withstand for long a fire that could incinerate all things.
For millions of years since that Great War of the Gods, both it and the black ring had been damaged during the struggles of those powerful beings. Its abilities in every aspect were not even one ten-thousandth of what they once were. If the black ring were willing to undergo Void Integration with it, it could have regained half of its original power. Even if it couldn't fully control the Sacred Flame, it would have at least been able to suppress it temporarily to prevent it from causing harm.
Unfortunately, such a hypothesis was impossible.
