What happens when Volibear Furious starts a combat at a location with one unit with less than 5 might and a Hidden Blade hidden there that kills him?

Ruling: If Hidden Blade resolves and kills Volibear Furious, his ability can no longer establish where "here" is and he won't deal the damage from his ability.

Sequence:

• Volibear Furious starts combat at the location
• Hidden Blade is played and resolves
• Volibear dies
• Volibear's damage ability fails to resolve because "here" is no longer defined
