Tzindylspar

Tzindylspar, the City of Rubies, was founded in -1715 DR by dwarves of Delzoun and humans of Netheril.

Geography
The mountain that marked the location of the city was unremarkable, one of many in the western Nether Mountains northeast of Silverymoon.

Inhabitants
Halflings also dwelt here.

History
A rich corundum vein gave the city its name and brief prestige. A portal was created connecting Tzindylspar with Calimshan, and a thriving trade in rubies commenced, lasting until the fall of the Cajaan dynasty in -1428 DR. Ynamalik Nadim came through the portal with an army of monsters and conquered Tzindylspar in -1427 DR. Between -665 DR and 620 DR, three powerful earthquakes collapsed the tunnels leading to the surface, opened passages into the Fardrimm, and killed various forces occupying the city.
