As those who had gone on the trip to 'Alternate Timeline 3' began filtering through the portal, Ishtar finished up with her 'training' -- properly focusing on a wellspring of Ki to help with her control -- and made her way over to watch; and from their faces it was obvious the trip had been arduous. Though without any overt signs of injury ... it seemed it had been more of an emotional struggle.
When the stone was finally carried through however, the Oni watched as the energy was siphoned out and back into its source, Zurvan, the Aspect seeming to recover some of what had been taken from him as a result.
... it was a start, at least.
"You seem too weak yet, to be left alone. So unless there is a reason not to, I will remain behind again." Ishtar commented, before turning away. Those that were going -- Her Saiyan included -- were capable enough to handle things, especially if the journey this time would be easier. No sense tiring out more, or worse, leaving Zurvan under-defended; when there was no need.
Especially with Grinthorn's true nature revealed.
