The Penumbral Plane is one of Tanares's signature environments, a dark mirror of reality, where the most horrific Tanarean aberrations dwell, embodying dark emotions and negative thoughts. Face the powerful, huge penumbral dragon in Adventure in the Realms of Madness or join his side on Dragon Collection's Boss v Boss Game Mode. The monsters all come with stat block cards and are tne most powerful villains we've designed for Tanares Adventures, as you'll face them in the new (Epic) campaign arc.
