In an overgrown jungle where monsters roam free lies the Second Citadel, one of humanity’s last strongholds in a hostile, hungry world. The people of the Citadel live their lives on the edge of a knife – knowing that any day a beast might storm their homes, knowing that now and forever the monsters are planning the final assault that will end humanity for good.

The only defense against a world that wants them dead are the Knights of the Crown, led by the Second Citadel’s Queen; and she has a very important task for her best knights. A strange cave has been claiming the lives of the people who live nearby… and if the Knights can’t find a way to work together, it will claim their lives, too.

Welcome to the Penumbra, dear Traveler. We hope you enjoy your journey.
