The tunnel opens out onto a rocky strip of seashore, perhaps a dozen yards wide at most. On one side, the ocean pounds relentlessly against the beach; on the other, a steep cliff towers overhead. A cursory glance, however, reveals that it's not a cliff, but a wall, in which is set a massive pair of wrought-iron gates. Something green, feathered, and the size of a large house is bashing itself against the inside of the gates, trying to force them open.

Cerberus bounds ahead of the group, turns to face the gates, and bellows a mighty "GRRRRROOOOOOOOOOWF!" at the feathered thing. It immediately backs off.

The smallest of the sheep-guards looks proud. "Good boy."
