You, my creepy friend, should just stay here in the Mangled Hound Inn – safe and cozy – and let the stories of foreign lands come to you. Have a pint of fresh celery wine and a plate of Moffings and let the gods be gods.

Sir, take my advice; stay here in a good Inn, safe and sound, and let the stories of foreign lands come to you. Enjoy a pint of fresh celery wine and a plate of Moffings and let the gods be gods.
