A Bell of Dethmoora, named after the late warlock Dethmoora Darkeyes, is one of the three tools needed to create a Circle of Greater Summoning.  When properly atuned with the Wheel and the Candle, these items conduct vast stores of arcane power.$B$BMy servant Gorzeeki can construct such a bell, but to do so he will need a large supply of elixirs of shadow power.  Procure the elixirs from an alchemist and bring them to Gorzeeki.
