Powered by the thrilling Adventure Game Engine, Fifth Season transports players to the Stillness, where their characters will have to work together to survive the cataclysmic Fifth Season, defeat dangerous foes, and protect their Comm from threats big and small. greenroninstore.com/products/fif...
A three dimensional rendering of the cover of the Fifth Season Roleplaying in the Stillness core rulebook, with the image of a woman on her knees, as power emanates from her, splitting the ground as shards of rock burst forth, and in the background a community is overshadowed by a massive mountain on the verge of eruption. The words PRINT + PDF are above the PDF rendering of the same cover.

This would be a great question to ask over at Atomicthinktank.com!
The words GET INTO THE are over a stylish retro-future Atomic Think Tank Logo spelling out Atomic Think Tank. To the left of the logo, a brain of mottled light blues and blue greens hovers, decorated like an atom, with the brain taking the place of the nucleus, and wrapped in the familiar bands of energy formed by the protons found in the typical artist's depiction of the atom.

Grayscale image of a lonely lighthouse sitting on a hill just beyond a foreboding forest. The neon yellow Titan City Serials logo visible in the top right corner. It's meant to evoke the Dawntower Lighthouse on the outskirts of the desolate town of Duskbrooke. A solitary beacon of light in a world shrouded in darkness and longing.
