Inspired by the "Happy Fun Ball" from the web series Critical Role, The Cube of Vanya is a magical adventure through demi-planes created by an ancient wizard, now destabilized by a malevolent dragon. The adventurers find themselves trapped within a series of themed planes with no idea how they got there. Navigating these planes to find a means of escape, they uncover the secrets of the cube while piecing back together their own memory. During the campaign the adventurers may fight shadow demons in an inn which is really a prison, flee a tornado while perched perilously in the sky, forge a weapon within a volcano, and much more. The module is structured in a non linear manner allowing the adventurers to choose their own way, or for the DM to pick and choose their favourite bits to highlight. The adventure was written with four level 5 players in mind but it would be easy to tweak for different sized groups around that level.

Note: This is a sequel to Out of Body, Out of Mind. The legend of the realm of Tirna'cel is well known. Once remembered for its power-mongering warlords, homunculi-wielding sorcerers, and archfiends from the deepest pits of the Abyss, Tirna'cel has become a powerful and welcoming land over the last 600 years, due in no small part to the efforts of the warlord Tirna'gael, a member of the land's founding nobility. But your party knows the truth. You ventured into the tomb of Tirna'gael some six months ago, and therein discovered that the fallen warlord was actually little more than his brethren: a petty, avaricious power-monger. Possessed by a rival force which also desired the kingdom - a rare incorporeal demon called a nescent, which inhabited his body and augmented his already incredible power to unforeseen levels - Tirna'gael sought to overthrow the ancient warlords only to replace them. Through Tirna'gael's augmented body, the nescent overwhelmed and eliminated the other warlords, eventually dominating the realm along. But before it could consolidate its rule and throw Tirna'cel into an even darker age, the secret of its power was discovered by the paladins of Garadon, a virtuous cell of justice and light. The paladins lured Tirna'gael into the center of his own fortress and trapped him there within a powerful anti magic field. His body withered and died but the nescent remained dormant, waiting for its chance for revenge. During your visit to Tirna'gael's fortress-tomb six months ago, you accidentally released the nescent from its prison. That enemy has since been vanquished - at least for the time being - but the memory of your pitched battle against it still lingers as you approach the original chapter house of the Order of Garadon. You have been summoned.
