Where's an Orb landing?

Nasuverse(Fate/Tsukihime)

The orb has found its way to the Nasuverse, home to Magecraft, vampires, Servants, and Holy Grail Wars. In spite of dwindling Mystery, the Orb faces no problems 'repairing' anything, be it magical or even divine in nature.

Now, where does it land? Does it find a greater grail like fuyuki, all corrupted cause SOMEONE (looking at you, Einzberns) messed with the system? A lesser grail like Ilya or Sakura? Or even an incomplete one like the Waxing Moon?

It could arrive in the world of Extra and integrate itself to repair the magical Matrix that is the Moon Cell. Or it could find itself in the world of Grand Order, and merge with a grail to become a 'properly repaired' Singularity, or possibly a whole new world by repairing the core of a Lostbelt?
