Cheza Betaze is the 17th Nekron urban area found in the Northern Cascades. The reasons why it is the best known of all Nekron cavern cities is that is has an easily accessible surface entrance/ exit which is just off the main Cascade trade trails. Being of recent construction in a time of prosperity, it is a city the Nekron feel proud off.
