Bleak Eternity of Gehenna (2020)

Publisher's blurb: Open these pages and learn about the volcanic plane of cruel intentions, the Bleak Eternity of Gehenna! The mythical Codex of the Infinite Planes is a massive book containing information on the very planes of existence. Too many for one document to tackle, so it's been divided up into volumes covering individual planes. Crack open the Codex in this continuing volume and learn about the Bleak Eternity of Gehenna, also known as the Fourfold Furnaces, where cruelty, selfishness, and greed walk together on volcanic slopes! Home to the yugoloths and a great number of other nasty creatures, Gehenna holds secrets aplenty above, on, and below the cliffs and mountainsides that encompass each dangerous layer.
