White Spire

In the world of Dota, White Spire is a race track or gambling institution, but described as a city by Valve in the announcement of Underlords.

"A smugglers paradise with loose morals and colorful residents to spare. Despite being overrun with syndicates, gangs and secret societies, White Spire has never descended into chaos for one reason: Momma Eeb. She was respected... She was loved... and unfortunately she was murdered last week. Eeb's death has sent one question rippling through White Spire's underworld: Who is going to run the city?"
