The Approach:

Those who find their way into the regions around Lith My’athar find them selves in rock hewn tunnels, some of dwarf design some by Drow design, but all made to get people from point A to point B.  The tunnels are roughly 30 feet wide  by 20 high with stalagmites upon their surfaces.  Winding for miles from the nearest unguarded surface entrances and exits the tunnels are a labyrinth of mazes and dead ends.  Very few who are not drow ever find there way to the city unless allowed or by sheer chance. Neither is a good option…..     
            

As one finally does approach the city gates he finds them guarded by several drow warriors on the outside.  The gates span the height and width of the tunnel, and remain closed at all times save for house members and expected guests...   If one traveler can properly identify the house he is seeking and the house has sent word to the gat for an  Arrival they may be opened but only for a short time.  IN addition to the guards outside the gate  there are several dozen on the inside of each gate along with several wizards and sorcerers that maintain constant watch on those outside via Scrying    crystals placed in the surrounding rock. These gates cannot be opened from the outside, by force or magic, thus makingthe first line of defense for the city. Shouold said gates becrushed by force or jammed open a second gate which also spans the Heigth and width  of the entrance tunnells will  can also be dropped completely sealing the innercavern off from the outer gate.  there is no going over as the gates are set into the tunnels.  The walls of the ever expanding cavern are littered with enchanted devices thatkeep out would be destructive spells from penetrating from outside the city, In many areas he cavern has actually been walled and enchanted mithrill adamantine alloys installed to ward off magic.
           
            
         

THE ENTRANCE

    Lith My’athar, a drow city beneath the spine of the world, acity posed ready to begin the onslaught on the surface world. A drow city placed on the banks of one of the few rivers within the underdark, the riverknown as Niar'haanin d' Renor Vlos.  This region of the underdark is ripewith resources and left alone by surface dwellers and underdark races alikesave for the drow and there servants/slaves that live there.  Known for itgreat Arial and seafaring navies (generally ships crewed by mercenaries andcommanded by drow sorcerers or other drow not put off by the great blinding orb) this drow strong hold is far from vulnerable. Surrounded by an evergrowing fortification of adamantite mithrill and other magically enchantedmaterials this city is virtually indestructible from any conventional warfare methods known to the world of Faerun. 

Like most drow cities the social order is maintained by aruling council, the council consists of a member from each of the prominenthouses and guilds.  At the head of this council sits My’rune Maeviirmatron of the first house of Lith My’athar.  The council meets once everytidal cycle of Niar'haanin d' Renor Vlos or whenever any dire need arises thatcalls for immediate decisions. The houses in this city do not compete with eachother as most drow cities do but they by the size of there standing armies andtheir prowess in battle.  That is not to say that there are not somesubtle more secretive assaults on other houses, but there is never any openwarfare. Though occasionally a house may try to destroy another in one fell swoop, these attacks are only acknowledged if they fail (in good Ilythiirimanner).   If a house is successfully destroyed the excepted shift inhierarchy is observed and life moves on.

                Guilds are also fairly common within the city and they function in and out ofthe underdark. The more prominent of these guilds also function as houses intheir own right when it comes to membership on the council. The most prominentof these guilds at this time is the Streea dal Har'oloth assassin’s guild. Mostguilds are given free reign to govern themselves as they chose so long as theydo not openly side with one house against another house.  To form a new guild the guild must submit a proposal to the ruling council, and the councilwill vote on the validity of the new guild. Only three of each type of guildwill be accepted.
