Boreal Emporium
From AmtWiki
Boreal Emporium was a joint business venture between Lord Covington Von Humphrey and his cousin Master Razalak Dragonsbane.
The firm was best known for its "bottomless potions": enchanted potion bottles whose contents would magically refill 24-hours after each use.
The company was dissolved in 2014, when both owners died of totally natural causes.
