Djerad Thymar Djerad Thymar ( the " Fortress of Thymara " < ref name = " AotT / Hardcover - p291 " > < / ref > , in Draconic ) was the capital city of Tymanther . It served as the cultural nexus for the dragonborn on Faerûn . Description . Djerad Thymar was considered by some as a renowned place throughout Faerûn for its incredible size , unique shape , and virtually impenetrable architecture . Unique in its design , the entire city was one giant hollow pyramid , that rested on a foundation supported by a huge number of columns . The top of the pyramid reached 1 , 500 feet ( 460 meters ) into the sky . A wide ramp was the only land entrance to the pyramid . The city was surrounded by a few farms and homesteads , as well as by the private states of the wealthy clans , which usually were built in Unther an ruins near to Djerad Thymar . Interior . Inside the pyramid , in the lowest level were a series of agorae that looked like rings around the columns , that served as the commercial area of the city . Although normal citizens had to use a series of ramps and stairs to get to the upper levels of the " djerad " , the most influential clans had access to teleportation rooms that allowed quick access to all levels of the pyramid . In the upper levels there were balconies leading to individual dwellings . Those dwellings were separated by plazas and atria that rose from the base of the " djerad " all the way to the ceiling . The interior of the pyramid was lit by magical lights that had the property to nourish the different kinds of plants the dragonborn used to decorate their homes . Government . Djerad Thymar was ruled by the Vanquisher , who also ruled all of Tymanther . In 1487 DR , the Vanquisher was Yrjixtilex Kallan . Military . The headquarters of the Lance Defenders , the primary Tymantheran military forces , were located in Djerad Thymar , and the Adjudicators served as the city ' s police force . < ref name = " AotT / Hardcover - p61 , 145 " > < / ref > . Aside from that , each clan and certain organizations , such as the Platinum Cadre , had private war bands that were called to protect the city when needed . The inhabitants of Djerad Thymar were also ever - ready to take up arms should the city be threatened . Economy . Djerad Thymar was a thriving city . The city ' s open bazaar in the Market Floor was full with shops and stalls belonging to farmers , craft - vendors and artisans from the city and from nearby villages and homesteads , and traders from other nations were allowed to sell their goods as well . Djerad Thymar was also known across Faerûn for its military schools on tactics , engineering , and unconventional warfare — particularly dragon - fighting . Their exotic martial techniques were imported from Abeir . Inhabitants . Dragonborn made up the bulk of Djerad Thymar ' s population , however a sizeable number of tiefling s were also common inhabitants of the Market Floor . Likewise , a minority of traders of many races were allowed to live in that level of the city as well . After the Second Sundering , a minority of mulan i refugees were allowed to live in the Market Floor and in the outlying areas near the city . Religion . There was no dominant religion in Djerad Thymar , with few individual dragonborn revering gods in their own ways . However , a few organized religions did had a presence in Djerad Thymar . The Platinum Cadre was allowed to spread Bahamut ' s teachings in the Market Floor and in the Catacombs .

Djerad Thymar was constructed as one the most important " djeradi " of the Abeiran nation of Tymanchebar , nearly two centuries before the Spellplague , although at the time it was called by another name . It was specially built to hold off dragon attacks , and eventually it became the capital clanhold of Tymanchebar . After the Spellplague transported Tymanchebar to Faerûn , the only " djerad " left mostly functional was Djerad Thymar . The ruins of Djerad Thymar fell on top of a granite ziggurat that was the tomb of the Untheric god Nanna - Sin . < ref name = " AotT / Hardcover - p402 " > < / ref > The goddess Selûne guided one of the surviving dragonborn of Tymanchebar , Kepeshkmolik Thymara , to the ruins and gave her Nanna - Sin ' s weapon , the Black Axe of the Moon ' s Champion , to help her to find other surviving dragonborn . The survivors , guided by Thymara , reunited in the ruined " djerad " and used a powerful artifact known as the Breath of Petron to fuse the ruins of the " djerad " , the ziggurat , and rocks from the Smoking Mountains , founding a new city they called Djerad Thymar in honor of their savior . < ref name = " AotT / Hardcover - p291 - 294 " > < / ref > The dragonborn then founded the realm of Tymanther with Djerad Thymar as their capital city .
