Knock

You hear a muffled but booming voice rumble through the doors. "Visitors? Wasn't expecting any."
You hear the bar on the door being removed, shortly followed by a scraping of wood and stone as the doors are parted. Through the growing gap you can see the tremendous figure of a Hippopotamus straining to pull the doors open. Even for such a sizeable species, he must be a giant! He stands nearly twice your height, and easily three times your width.
"Hello! I’m Obie! Wait, the viscount didn't tell me he was expecting anyone. Are you supposed to be here?" He has the beginnings of a suspicious look in his eyes, and his hand rests on an enormous hammer hooked on his belt.
