I haven't gotten mine yet, or read the pdf closely enough, but apparently there's some translation anomalies in the rules. But hey, I have enough OSR clones, this one will stick out as the "interesting read".
Apparently there are (or were) two different Wiecks and the one heading Nocturnal was Stewart, who apparently passed away last summer, and his widow now owns the company and Stephan is now acting as publisher.
Stewart had plans to pick up the next boxes in the series, but I've not heard any further updates since then: they're still in the process of fulfilling the other KSers that were pending, I think, for a little while.
