Probably around 2000 BC, in the height of the bronze age. Kobolds are ascetics anyway, so the lack of modern marvels won’t really affect us much, and since we prefer to live underground, this seems like a pretty ideal time period - decent tools are available, but we’re a long ways off from any kind of industrialization or large-scale mining that would cause all of you surface-dwellers to disrupt our homes.
