From publisher blurb:
Interesting and Mysterious Things for Any Fantasy Game Where the Heroes Might Wander a City
Designed specifically for people playing 5e campaigns.
Continuing the combination of utility, imaginative content, and deep research found in Unpleasant Discoveries and Feywild Discoveries, Evil Beagle's resident scholar and master-of-cleverness, Michael Surbrook (AKA "The Professor"), brings another useful toolkit to bear for Game Masters who want to elevate their games. In this case, City Discoveries is an extraordinary source of encounters and other useful information about using cities in your campaign, including -
Elements of a Medieval City: Discussing rivers, walls, streets, business, residences, and so much more.
The Look and Feel of a Fantasy City: How best to describe the sensory experience of entering and exploring a city. This includes special elements unique to the cities of various races and cultures found in many D&D settings.
City Set Pieces: Concise descriptions of key places city wanderers might come across, including castles, docks, guard houses, inns & taverns, and more.
City-Based Adventure Seeds & The Encounters: A huge list of potential story arcs and specific encounters the GM can choose or randomly generate to enhance any trip into town.
That last part is the true meat of the product, as it can enhance any fantasy game with a couple of simple rolls, making it an invaluable tool for any GM hoping for some quick-and-easy help in elevating their scenario with the mundane, magical, and mysterious aspects of city adventuring.
