Two brilliantly chromed cylindrical towers stand side by side, one slightly taller than the other, their glass domes brush the clouds with their height. Before the perfectly manicured grounds, there stands a sign. Etched in a mirror, it reads:

Welcome to obsidian's Silver Towers

These sleek towers are made of an impenetrable silver mirrored glass that shines brightly during the day; during the night they are a display of their own with glistening lights from each window. Glass elevators climb to the 99th floor. Here is where the Silver Towers connect from one tower to the other via a tunneled walkway made of the same silvered glass.

The East Tower is the location of the office of obsidian's assistant Crystal, the boardroom, the kitchen, and other assorted offices. The East Dome is an atrium full of exotic flowers and plants, which visitors can enjoy from below as they await their appointments or meetings.

Across the glass walkway is where obsidian's offices are located. obsidian's private office takes up the entire upper level of the West Tower. The circular room is furnished in the softest of white Italian leather chairs, with end tables and coffee tables made of silver lace obsidian. Hidden behind paneled walls lies a fully stocked bar and the latest in entertainment systems.

A spiral staircase winds up to the Dome. The Dome is constructed completely of glass, and provides a 360 degree view of the City. Here is obsidian's workplace, in a loft, with nothing more than a desk, a comfortable chair, and a panoramic view of the City.

A box of leaflets sits against the wall, with a notice, "Please take a leaflet for more information."

Lair moved from Obsidian and 50th, or was originally misreported as being there. Note also that the very last paragraph was added later; credit to supplying it goes to RCPedia.
