The region known as Nach includes Loch Nach at its center, the jungle to the northeast, and—most notably—Brackhaile, the village where Ada-Adora hails from at the beginning of the book *Shadows: The Clockwork Army*, and which later, following the construction of a fortress of the same name, becomes the seat of the throne of Gael I of Tahumeria.

Nazacha, the City of the Serpent, is a key, bustling trade hub situated in a strategic area—bordered by Tahumeria to the west, Ashantia and the Tanato of Qsim to the east, Norori Riki to the north, and Nahendra to the south. It is home to the great Temple of the Serpent and a place of spells and occult magic. For many years, Jacques Habad—the Grand Clockmaster—resided there, until he accompanied Ada north on her odyssey to recover her stolen Shadow.
