I did a little search and this is all I found https://archive.moe/u/thread/1509666/, so if the site is down for a while, he must be too busy with his life to continue updating and using it or he abandoned the sequel and the site to go live his life, we will probably have to wait some years to discover what happened, the sequel will either be released eventually in an unknown future or never and be forgotten.
I don't know if it is related to Wulfhammer.org but you can download here http://aeresland.net/ all versions of Embric of Wulfhammer’s Castle and a teaser of Marquess of Notoriety.
