What happens when "Weave Together the Fabric of Place" expires with the Incarna of the Lair Aspect in the woven land?

The Lair Incarna moves to one of the constituent lands – an Inland one if possible. All Invaders, Dahan, Beasts, and Presence in the combined land move with it if possible.
The Presence of Ocean's Hungry Grasp will generally be unable to move with the Lair Incarna, and the Presence of Volcano Looming High might be unable to do so; in both cases, that Presence can move to a different constituent land instead in order to satisfy its own movement restrictions.
