Garadon Manor (d20)
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 to the efforts of the warlord the realm of 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 discovered that the fallen warlord was actually little better than his brethren: a petty¸ avaricious power-monger. Possessed by a rival force which also desired the kingdom - a rare incorporeal demon called a nascent¸ 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. During your visit to Tirna'gael's fortress-tomb six months ago¸ you accidentally released the nascent 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 house of the Order of Garadon. You have been summoned.
