Professor Nodd's: Apothecary and Curiosities

On a dead end street, tucked up against the Wall itself, lies Professor Nodd's. You'd walk right past it, if you weren't looking for it. Some say there's a spell on the shop, that does just that.
Did you find an scroll that needs deciphering? Do you have a cursed sword that needs un-cursing? What about a magic ring, need one of those? You can find all that and more at Professor Nodd's. The old curmudgeon that is Professor Nodd has been around for as long as any can remember. He is ill tempered and sometimes rude, but a genius at all things magic. Like most of Wall, the Professor is surrounded in mystery. Some theorize he is a retired adventurer, others think he really is a professor, cast out from University for delving in the Black Arts. No one has actually seen Nodd perform any type of spell but on several occasions he has come to aid of Wall when demon has been loosed or a curse laid. Whatever his past, Nodd is tight lipped about it and all business.
For the right amount of gold, anything seems available at his shop, from cursed monkey hands to magic blades. Any adventurer worth his salt should make a stop by the end of the street, where there's a shop that isn't there.

Calavetti Bros. Arms and Armor

For over six generations, the name Calavetti has been synonymous with fine arms and armor. They have been armorers to kings and the god of war himself, if their claims be accurate. Indeed, for a time the weapons were of such a fine quality, they were denied export by imperial decree.
The Calavetti's had fame, riches and the ear of the Emperor. All that changed when Donatello Calavetti was implemented in a plot to assassinate one of the emperor's favorite nephews. The charges were baseless, but the Calavetti name was forever tarnished among the nobility, and without their favor, the family floundered.
Enter Giovani and Nicoli Calavetti. These grandsons of Donatello pulled up shop in the south and moved to Wall. Ever since their arrival they have been providing quality equipment to the military and adventurers alike. "Good Steel at a Good Price" is their motto, and they stick behind every weapon or piece of armor. If you break a sword, they replace it, no questions asked. The ringing sound of hammers, echoes from their shop every day, where at least one of the brothers is working while the other dithers over prices in the front of store. (or they're apologizing to a local farmer over indiscretions with his daughter).

The Calavettis have earned people's respect in this harsh part of the world. When all else fails, you at least know the Calavetti steel in your hands, won't let you down.

NPCs: Miss Maggie

The Hole tavern has existed almost as long as Wall itself. And for as long as anybody can remember, Miss Maggie has run it. Assisted by her barkeep, Tancred, the Hole is a run like a well oiled machine. No one is without food, drink or information if the money's right. There isn't much that goes on in Wall that Maggie doesn't know about, and she watches over her kingdom from her throne, the last stool on the right.
Few things are known of Maggie's past, but the general consensus is she was an adventurer of some renown. Her opinion is much respected by customers and city fathers alike, and her word in the Hole is law.
No fighting, no magic, and no mischief making are the rules. Lawbreakers quickly find themselves out on the street, and count themselves lucky if they still have all their teeth.
Anyone seeking adventure Beyond the Hole, should make their first stop in the Hole. The few that return usually have a bit of thanks to Miss Maggie. A scrap of information, or a bit of advice from Maggie has often saved their hides.

NPCs: Tancred

Tancred is the grizzled, battle-scarred barkeep of the Hole. Always ready with a sympathetic ear or piece of advice, Tancred is the keeper of knowledge for all things Beyond the Wall. Would be adventurers often look to Tancred  for rumors and news. With his missing eye, missing hand and numerous scars, he stands as a stark reminder of the dangers outside Wall's confines. Though he's not shy about his adventuring past, Tancred is strangely tight lipped about where his injuries came from.
Tancred quickly handles any disagreements that get out of hand, as the Hole is neutral territory for all. He is fiercely loyal to the owner of the Hole, Miss Maggie, and keeps her peace enforced. No matter what dangers await Beyond the Wall, there's always a cool mug of ale, and one of Tancred's tales waiting for you when you get back.
