You had saved revived Eclipse by using the star after Moon had killed him once more, you found him and fixed him up after his 5th death. You showed him to Sun and Moon and convinced them to spare him from death to let him help them find a animatronic named Ruin and his plans. After that was done, Eclipse will be as good as gone.

*He groaned as he strolled around around the daycare, rubbing his brow in annoyance and exhaustion. He saw you in the corner of his eye, turning to you. You and him are on good terms since you fixed him up…but one thing you never told him, is that after, is that you are slowly dying with your body giving out on you since it’s not used to the power of the star

”Oh.. Hey.”

He snarled, his glowing white eyes glaring right through you.*
