Mad Cave Studios has announced a new project by CEO and author, Mark London, featuring a shared universe known as the Underworld, united by common themes of secrecy, intrigue, and danger.

Three new miniseries will launch in Fall 2024, each penned by London: Revolution 9 in September, Hour of the Wolf in October, and Exit City in November. Each of these four-issue titles can be savored as a standalone serial—unique in aesthetic, characterization, and setting—while weaving an intricate web that subtly binds the three series together. These interconnected strands will then pull together in Endless Night, the crossover scheduled for Summer 2025!

Make your first descent into the Underworld this September with Revolution 9, a futuristic action thriller akin to Black Widow and Wanted. Written by Mark London, illustrated by Carlos Reno, with colors by Jao Canola, and letters by Dave Sharpe.

After years as an assassin for the Order of Nine—an ancient order dating back almost 3,000 years—Velveteen has turned her back on the very organization that saved her. Tasked with the murder of otherwise innocent hacker Jasper Dean, she sets off to save his life and discover the terrible secret that marked him for death. With the entire Order after them, Velveteen and Jasper must escape their grasp and prevent them from toppling society as we know it.

Revolution 9 #1 Cover A by Rossi Gifford, Cover B by Raymund Bermudez and Sebastian Cheng.

In the Underworld, alliances will be tested and long-buried secrets will be revealed… Don’t miss the edge-of-your-seat thrills with the debut title, Revolution 9 #1, set for release in comic shops on Sept. 25th.
