Adrilanca is (on paper, at least), a plutocracy that controls a thriving port city and a significant amount of surrounding farmland. Most of its water supply comes from a network of aqueducts that direct the water from near-ish mountains.
Major events include a near poisoning of most of the populous that was foiled by a rag-tag band of adventurers and one of their moms, as well as when a significant portion of the harbor district was devoured by an ancient worm-like entity that had up until then been worshiped as a god by a cult that was hiding out in the sewers.
The city was introduced as the home town of Aristobulus Ravenscroft, whose player, Matt, is a fan of the Khaavren Romances series of novels.
Crash has never read these novels so its development as a city likely bears only a slight resemblance to what’s portrayed in the original source material, and he prefers to keep it that way.
