Fane of Shadows The Fane of Shadows was a that journeyed the worlds on the currents of the secret Weave . The place had many names in many tongues , and was also known as the Temple of Night or the Umbral Shrine . Location . Created by Shar , it served as many dark gods of many worlds , and as a gift of the god of shadows to their faithful ; a sanctuary that journeyed through time and worlds . It also served as a bastion and armory for the servants of the twilight . It was located within the Lightless Lake ( the Moonmere ) in the Gulthmere Forest , but it only materialized during a certain date at midnight , and stayed only temporarily in each world for a short time . Upon its arrival onto Toril , the Fane appeared within the depths of the Lightless Lake in a diffuse , ochre light . The entirety of the temple was situated on an invisible platform encapsulated within a dome of air . The architecture included black - veined columns , graceful arches , and thick pillars all crafted from marble , basalt , obsidian , or ebony . The Fane of Shadows was guarded by a host of shadow s inside the courtyard area . They were only hostile to those not subservient to shadow . Interior . The courtyard contained a statue garden of hundreds of obsidian sculptures , all of them depicting the innumerable world ' s gods of shadow . Statues of Toril ' s deities of night and shadow , Shar and Mask , were among the collection . Beyond its doors it contained a long , wide hallway , the Grand Hall , filled with shadows and bathed in a low , green light . Painting and mosaics lined the walls , while tables and pedestals were hidden inside alcoves along it . These alcoves usually held an item of great power , one of the many gifts of shadow found within . Only one gift could be taken from the Fane of Shadows . A husky , female voice tried to persuade its guests in a perceived , familiar tongue into taking an item of power . The Grand Hall also contained the caretaker of the temple , who materialized from the shadows . He was an elderly man , with solid black eyes , and his duty was to serve his calling into the shadow . The hallway ended at a pair of double doors , which led into the inner sanctum . The inner sanctum contained a skydome ceiling of black encrusted in gem s , representing the night sky of the world in which it then existed . The inner sanctum itself had a polished slate floor inlaid with an amethyst border , and in its center lay a black sphere bordered in purple : Shar ' s symbol . A horseshoe - shaped altar lay in the center of the symbol on some kind of black crystalline substance , under an area of ceiling of the blackest black , depicting Shar ' s moon . It was underneath this symbol where a host received the transforming energy of the greatest gifts offered by the Shadow Weave : the transformation into a shade . Black curtains lined the walls of the inner sanctum , as well as a mosaic of the Weave Tap . Entrance into the Fane of Shadows required either being adept in the Shadow Weave , or reverence to a god or goddess of shadow . Erevis Cale . Erevis Cale was on a mission to stop the shadow adept , Vraggen , from taking the greatest gift from the Fane of Shadows and transforming into a shade . Vraggen ' s band of members ( Azriim , Serrin , Dolgan ) betrayed their comrade and killed him before the transformation into a shade occurred . Instead , they found and took the Weave Tap , a sapling with smooth , black bark , few gray leaves , and three oval , silver fruits , hidden behind the mosaic replica . Erevis Cale stepped onto the altar to transform into a shade in order to prevent his death . In doing so , he gained the powers of immortality , regeneration , and agelessness . He also received a tome of history and knowledge pertaining to his calling from the caretaker .
