Cobb and Webb's

A competitor of Borgin and Burke's, this shop also sells dark artifacts. However, Cobb and Webb's seems to have found its niche in spider-related memorabilia, including selling a large variety of oxic spiders for pets.

Markus Scarrs

Markus Scarrs Indelible Tattoos is one of the only Wizarding tattoo parlors. They specialize in tattoos with more macabre themes, so if you have a preference for a genre outside of horror, you may want to find someplace else to go.

Moribund's

Despite its rather innocuous storefront, Moribund's is one of the most dangerous places on earth. It serves as a meeting place for vampires, and earns its money by charging its inhabitants a fee to feed on whatever other unsuspecting soul may walk through the door.

Msaw Ætare

To the casual observer, Msaw Ætare appears to be a shop that is always closed, since its front door is always locked. However, when one steps on a particular cobble at the shop's front step, a tunnel will appear to lead you to an underground cavern full of nocturnal and Dark animals available for purchase.

Shyverwretch's

Shyverwretch's Venoms and Poisons is the easiest place to go to for poisons. The Ministry has enacted a special identification checking program, and all poison purchasers are logged in a large tome locked in the back room of the store, so be careful with your victims, or you may be sent to Azkaban.

The Spiny Serpent

The Spiny Serpent is a wizard funeral parlor and crematorium. They promise to work quickly and discreetly, and are excellent at covering their tracks, in case you should want to hide that somebody has passed.

The Starry Prophesier

While Divination's reputation has certainly slipped in the Wizarding world, there are still people desperate for glimpses of their future, . The Starry Prophesier offers a person a chance to see their fate, though whether or not that fate is meant to be remains to be seen...

Tallow's Toxic Tapers

Formerly known as Tallow and Hemp Toxic Tapers, this poisonous candle shop has been renamed following the unfortunate discovery that one of its founders was a Death Eater (and subsequent pressure from the Ministry to do so). The candles sold here have a variety of adverse effects, from inducing headaches to causing "accidental" deaths.

Trackleshanks Locksmith

If you're going to Knockturn Alley, chances are you'll leave with something that needs good protection. Trackleshanks charges a pretty penny for their services, but their locks are nearly unbreakable and will surely protect anything precious.

The White Wyvern

One of the larger pubs in Wizarding London, The White Wyvern is famous for its potent alcoholic beverages. It also doubles as a gambling ring, though all payments are made under the table.
