Aside from House Drachall, how many houses are there currently?

Also, are there any settlements outside of Steinplatz? Whether known or otherwise?

There are lots; though it's not something I ever felt the need to define myself. Drachall is part of the worlds canon because of the way it dwarves the others in size and power; the other houses are for the players to create, in the same way they would a Human or Dwarven family.

There are no other known settlements on Rotsanger; the terrain is too unsuitable. This is a lot of what keeps the lesser houses in Steinplatz under the rule of Drachall, rather than leaving and starting their own settlement. Steinplatz has been the home is Nosferytes for as long as there have been Nosferytes on Tyrrania, and that's unlikely to change.
