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.

Here, Iuz will achieve his mad dream by destroying the imprisoned master of that alien citadel: Vecna, the mightiest lich, an immortal demigod.

An ancient legend, a missing wife, and a broken heart that time won’t mend. Part 4 of the Evenflow Saga

Do you want your players to feel like they are in a zombie movie, struggling against a deadly horde that tries to surround them, overpower them, and bear them down to the ground to be devoured? This is an adventure that can threaten even the stoutest of characters, and is not recommended for parties of levels 12 or below unless they are larger than normal. This module is designed to take 4-8 hours of play and cover a single day, depending on the party’s speed of play and how thoroughly they decide to explore. It includes suggestions and some plot hooks that can be used to tie this easily into a variety of long-running campaigns, or it can be run as an indepdent adventure. The players will come upon a sacked town, figure out what happened, track an item whose theft has ominious implications for the region, and explore a partly-flooded old temple to end the threat. It's primarily combat-focused, but there are a few areas where exploration and route choice makes a difference, as well as traps if the party goes for the optional temple treasury. The antagonists in this module are mostly ghasts and ghouls, but the module title and cover page are deliberately selected to not spoil this. These are greater ghouls and ghasts that can challenge higher-level characters, backed up by mobs of lesser ghouls that can surround, paralyze, and devour the weak and unlucky, led by a Warlord whose aura can drive even the stout-hearted into forgetting their plans in a moment of madness.
