Chamber of Aspects The Chamber of Aspects , also known as the Chamber of the Aspects , is a secret chamber where the five great Dragon Aspects would convene whenever they wished to meet . Background . It was here that Neltharion revealed the Demon Soul , his solution to ending the invasion of the Burning Legion , and urged the other Aspects as well as their respective flights to give up a portion of their essences to power it . Unknowing of his plan , they did so — and enslaved themselves to Neltharion ' s will . In " The Well of Eternity " , the Chamber of Aspects was described as " . . . a vast , monumental cavern , so expansive that even Alexstrasza appeared as little more than a gnat in comparison . " The Chamber ' s walls were featureless and frictionless , smooth yet curved , the floor was an immense flat circle that was geometrically flawless , and it was lit by a golden illumination with no source . Presumably , the Chamber of the Aspects was located somewhere in ancient Kalimdor ; its exact location before and after the Sundering was unknown ( Until " Wrath of the Lich King " ) . Later information suggested that the chamber was accessible anywhere the Aspects chose , but was mostly done in the most remote of places , away from prying eyes . However , one trying to enter had to be flying , as Alexstrasza and Korialstrasz did . The Chamber of Aspects underneath Wyrmrest Temple is in fact the Chamber in which the Aspects met . The Chamber in " The Well of Eternity " is not a completely different and more private place . At least some dragons consider the location related to a dragon ' s afterlife . In the battle with Yogg - Saron , a vision of Deathwing creating the Demon Soul here with the other Aspects can be seen . World of Warcraft : Wrath of the Lich King . In " " , the Chamber of Aspects is the location of a single boss raid encounter , similar to Onyxia ' s Lair , with the ability to add more encounters . The instances are titan in style . It now appears to be a small antechamber beneath the Wyrmrest Temple in the Dragonblight of Northrend ( which more or less contradicts the description made in " The Well of Eternity " ) . There is a meeting stone in the center of this room . It is implied from its design that there will be at least five bosses , with one for each flight , as there are five gate points which all have two guardians of each flight . As of patch 3 . 3 . 2 , there is still only one instance and the mystery remains as to why would mortals fight against the last three good - aligned dragonflights ( a question that has been answered somewhat by the announcement of patch 3 . 3 . 5 ) . Obsidian Sanctum . The Obsidian Sanctum is the black dragonflight area of the Chamber of the Aspects , available from the start of the expansion . It holds one raid boss — Sartharion . He is joined by three allies around the instance — Shadron , Tenebron , and Vesperon — who will assist Sartharion if they are not defeated . Ruby Sanctum . This chamber was opened in patch 3 . 3 . 5 . A powerful war party of the Black dragonflight , led by the fearsome Twilight dragon , Halion , have launched an assault upon the Ruby Sanctum beneath Wyrmrest Temple . By destroying the sanctum , the Black dragonflight look to crush those that would stand in the way of their master ’ s reemergence into Azeroth and to ultimately shatter the Wyrmrest Accord – the sacred bond that unites the dragonflights . The battle that is to come will surely deal a crippling blow to the Red dragonflight , however , it is up to you to stop this unprecedented offensive and defend the Ruby Sanctum . First you must face the assault of Halion ' s servants , Saviana Ragefire , Baltharus the Warborn , and General Zarithrian , before squaring off against Halion the Twilight Destroyer , a new and deadly force in this realm .
