The sea has many perils. Are the treasures of a sunken pirate ship worth the risk? Arkos Seatamer, a privateer and the sole survivor of a shipwreck has gathered a new crew. He's returning to the wreck to recover the body of his closest friend, Devek Harpwind, for a proper burial. Arkos had rammed the pirate vessel 'Striking Shadow' in combat, shattering its hull.

The pirate queen wore a cursed gold armband, shaped like a coiled eel. The sight of the band made Arkos mad with greed and he moved to slay her to take it. Devek tried to intervene but Arkos killed his friend in rage. With his dying breaths Devek laid a horrible curse upon Arkos to become a were-eel each night. The PCs are hired to accompany Arkos and his crew to the wreckage and recover Devek's body from the wreck, along with the armband he still lusts for. Pgs. 18-35

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.
