In her comfort Centra lost control...

In her comfort Centra lost control, her head became heavy, eventually she laid over on her side. And fell asleep. It was a much needed sleep.

This was a very large moon, large enough with just enough gravity, and Centra was on top of the moon on the side furthest away from Voryon, so Voryon gravity was also holding her in place. Centra didn't realize it but this was to her advantage.

Streckna took leave of Sieffas and flew off around the inside of the moon and then breached the underside and went out. Streckna couldn't see Centra anywhere and couldn't hear her thoughts. Streckna started to fly among the nearer moons to see if Centra could be found. Streckna was still concerned the vorion might do some damage.

The moon gravity was light and continued to turn slowly, eventually turning to put Centra closest to Voryon opposite of where she was when she landed. Centra lay there quietly. If she had not been sleeping and had let loose her grip she could have pushed off easily and broken the gravity and start her fall again, but she lay there quietly and nature kept her where she was until she woke.
