Mountain Home (Volcano Looming High)

If an inland and Coastal land get Woven Together by the Fabric of Place, can Ocean leave their Presence inland during Time Passes?
No.
The joint land is Coastal, but the split when Weave Together the Fabric of Place expires is considered a move, and Ocean's Presence cannot move to an inland land.

How does Reach from the Infinite Darkness work with Presence from Spirits with restrictions on where they can move Presence?
Since Reach from the Infinite Darkness ignores these restrictions, Presence from those Spirits can be abducted without any issue. However, that Presence can only escape to lands that it could normally be moved to, whether Coastal lands (Ocean’s Hungry Grasp), Inland lands (Lure of the Deep Wilderness), or Mountains (Volcano Looming High). If Breath of Darkness Down Your Spine doesn’t have Presence or its Incarna in any legal lands, you must choose to let a different piece escape or lose the game.
Every Growth option has a way to add or move Presence or the Incarna into a new land, so this generally won't be a loss threat unless multiple such Spirits have their Presence abducted and Breath of Darkness Down Your Spine is unusually low on Presence.
