When a showdown on Vilemaw's Lair (which prevents moving back to base) ends with both players still having units on that battlefield, what happens to the attacker's units that would normally have to return to base?

Ruling: The attackers return to base normally because recall is not a move, so Vilemaw's Lair's "can't move" restriction does not prevent the recall.

Nuances:

• Vilemaw's Lair prevents moving but does not prevent recall
• Recall is mechanically distinct from moving
