Zog's Arcane Farrago

Publisher's blurb: This collection of magic items is sold by a wacky mage named Zog, who operates a shop on Hillock’s Court in Waterdeep’s Castle Ward. The house he owns appears distorted from the outside, and usually there is some sort of riddle visitors have to solve before they are allowed to enter. At other times, Zog creates portals to random places in the Realms to allow passersby a glimpse at his wares. Strangely enough, this happens more often than not to adventurers with heavy coin purses. Once upon a time, Zog was an adventurer himself, but retired when he grew too old. His favorite past time as an adventurer were the drawn-out, emaciating haggle sessions, during which he sold the group’s findings or acquired new items. So he decided to dedicate the rest of his life to commerce! When Zog welcomes guests and possible customers, he offers them tea and plays the part of an absent-minded and slightly mad wizard. Alas, after many decades Zog convinced himself that his performance was a mere act. Actually, he is madder than he realizes and tones his antics down while customers browse his displays.
