This part is less thoroughly developed - fewer dense networks of houses and markets and shops, though there's a bloom of city around the western gate. The west part of the city seems designed for more than just dwarves, doors often having handles at two heights, artfully crafted flowing benches that could easily accommodate a short dwarf beside a tall elf. Far more of it's designed to be brightly lit, with more attention to artificial lighting (including some still-glowing magical lights) and carefully introduces shafts of sunlight or moonlight that fall on the remnants of small gardens. The architectural design's different, too, a distinct blend of angular classic dwarven lines and flowing shapes. The ceiling of the broad main avenue is an exact replica of the sky outside thousands of years ago, softly glowing crystals in place of stars.
The west gate is shut, and includes a mixture of two scripts - Elvish and Dwarvish, by the look of them - engraved into the arch over the doors. It, too, is designed to be held against invasion, but the paranoia is distinctly less than the kill corridor of the east gate.
The west gate opens at a touch - not, apparently, locked from the inside, though no latching mechanism is actually visible.
