City of Torment

Lovecraftian horror meets the Forgotten Realms in this second installment in the Abolethic Sovereignty series A tenday has passed since the gruesome battle against the kraken. Accompanied by two crewmates of the Green Siren—mage Seren Juramot and Captain Thoster—Raidon Kane launches a search for the warlock who has stolen the Dreamheart. But just when Japheth is within their reach, he escapes to the Feywild, leading Raidon and his companions on a dangerous journey into the subterranean city of Xxiphu. There, they hope to find and slay the Eldest, a great and powerful aboleth that has the power to destroy all of Faerûn.
But they aren’t the only ones bound for the hidden city. There are many others, both friends and foes, who have designs of their own on the Eldest—if they all don’t kill each other first.
