Letter of the Fallen Ranger

A trembling hand has scratched these words upon a soiled sheet of paper: "If you are reading this, then I am surely dead. Please deliver this letter to any Pathfinder lodge, or if that is impossible, to any temple of any deity. Do not allow my death to be in vain! My name is Manush Vuvk, and I have been a member of the Pathfinder Society for twelve years. I joined a team of so-called adventurers without having the slightest idea what an abyss of secret wickedness they concealed behind their valiant facades. The party is led by a certain Tioko Sakasama. She presents herself as a priestess of Desna, but takes no effort to hide the fact that she once served Lamashtu, and still bears the stamp of her true master upon her face. Why did she have to bring us to this accursed dungeon? It's clear as day! She's preparing a bloody ritual sacrifice. I still don't know who among our party will hold the dagger beside her, and who may lie on the altar next to me. But Liafella Dmerre is another servant of evil. Of that there can be no doubt. She and Tioko constantly argue, and their seething spite unites them like nothing else could. Liafella struck me for no reason, and would have killed me for certain, if Tioko hadn't used a spell to paralyze her. Of course, the sacrifice must remain unscathed until the ritual! Rubgen Drass is also an apparent cultist. With the tenacity of a maniac, he keeps dragging us further and further into the fetid depths, promising countless treasures – though by now, none in the party believe him... And no one can answer the simple question: why did we come here? The only one among them who might not be a dark cultist is Smaragda Ferdu. Like me, she trusts no one, and keeps to herself. She doesn't eat from the common pot, and keeps mumbling something about poison. Could this mean that she's meant to be a sacrifice, like me? Or is she their chief surgeon? Does she feign to earn my trust? Is it all to end in betrayal? I have no hope of escaping this dungeon alive. But I cannot accept the atrocities that these three or four villains are committing, to glorify their evil goddess. It must be stopped! Whosoever reads this note, find them and punish them. Do not allow them to discredit the good name of the Pathfinder Society!"
