When an attacker is stunned by Facebreaker at Vilemaw's Lair (which prevents units from moving to base), can the attacker return to base during cleanup?

Ruling: Yes, the attacker returns to base during cleanup. Attackers who are stalled in combat recall to base, which is not considered a move, so Vilemaw's Lair's restriction does not prevent it.

Sequence:

• Attacker moves to Vilemaw's Lair to initiate conquest
• Defender plays Facebreaker, stunning both units
• Units remain at the battlefield
• During cleanup, the attacker recalls to base (not a move)

Nuances:

• Recall is mechanically distinct from moving - it places units in base but does not count as a move
• Vilemaw's Lair only prevents moving from the battlefield to base, not recalling
