The man in black

You call the figure -- who turns out to be a man in black carrying a large sword, riding a horse -- over to you. You ask him what he's doing in these parts.

> I'm about to rob the Vault, he says.

> I hear there's untold treasures inside.

You yourself have no idea what's in the Vault, even though you guarded it for years.

Reveal yourself as the guard of the vault.

Wish him good luck and watch him ride inside.
