This particular soul stone is bound to the dark elven demon known as Undaerin (Oon-dayr-in). Undaerin is a godly being to the planar, dark elf-like beings known as Draelith who inhabit the plane of Charnaggen d’Oloth (The Black Scriptures, page 124). Undaerin is a godly being through his prowess in the arts of necromancy, dolormancy (pain magick), and umbramancy. His magicks have given him a powerful ability to split his soul and his body into two separately acting entities which act with the same mind. Such power is something even Zazazel himself wishes to attain for himself. While Undaerin’s physical body inhabits and conquers a large domain in Charnaggen d’Oloth, his Spirit is commonly found in ritual spaces with Zazazel or with Ibin of the Zhanith, further advancing the power of their magicks in the planes – seeking to empower all Disciples of the dark arts in various and new manners. This soul stone talisman places the Disciple’s soul beside Undaerin’s; bestowing various graces and empowerments of Undaerin’s own creation that will undoubtedly lead to an amazing progression of mastery.
