According to Ashie, the Tanren Undercity is an extension of the region of Tanren and not its own region. To prevent the spread of false information, please remove any references that state that the Undercity is a region. In its place, refer to the Undercity as it is or as an extension of Tanren.

Thank you for your cooperation.
