The Invulnerable Vagrant

The Invulnerable Vagrant is a magical shop in Zadash run by Pumat Sol and his simulacra. This shop is an annex of the Cerberus Assembly and was generally open from sunrise to four hours past sunset.

Exterior
The Invulnerable Vagrant is a large building of stained wood with green-gold velvet hanging on the outside was magically warded and was thus seen by the Mighty Nein to be untouched by the elements.

There were slits of glass in each of the doors that revealed a warm lit interior glowing from the inside out. Above these doors, carved delicately into a wood placard, was the name of the establishment.

Interior
The interior of the building was quite warm and was well-lit by lanterns that floated in the air. These slowly gyrating lanterns contained candles within them which flickered together as though a wind was blowing over their flames.

The inside of the chamber had a long table with a few small books laid out, and on a velvet raised platform looked to have been a long rapier, jeweled and gorgeous. On the back wall there was a shelf filled with many books. In front of this shelf was a desk. There were glass cases at the far end of the room.

Patrons

 * A portly looking middle-aged gentleman, with curled and unkempt hair, pulled close to his scalp.

Pumat Sol insisted that this establishment required cleanliness of its visitors, forcibly cleaning Caleb Widogast with a Prestidigitation cantrip when he was judged to be insufficiently clean. Pumat Sol ran a business for profit that dealt in the sale, trade, craft and enchantment of magic and magic based items. Although they had an assortment of all manner of items, Caleb had suspected that the shop dealt with mostly used items.

Trivia

 * The shop's name is likely a reference to "Murder Hobos". This term is used affectionately (or sometimes pejoratively) to refer to Player Characters in role-playing games, as such characters are typically homeless transient vagrants, who do not hold regular employment while possessing powerful skills and abilities.
