I haven't posted in quite some time. Long story short, it never sat well with me the way that Shadowsfall ended and I always wanted to come back to it. I've been thinking alot about it over the years, thinking how I would do have handled things differently if I did it again.
Short answers: alot more adventures and don't give up. I only did the 1 adventure for shadowsfall and frankly it didn't really take place on shadowsfall as much as happen to be there. That would need addressed. Also, since the players guide, we only released the guide for umbral kobolds. We need to detail far more of the races, giving them details as well as class options. Plus the setting needs developed more, let you immerse yourselves in the area, drinking it in.
Well, we're starting up a few test balloons. For the next year or so, we are focusing on mid to high level adventures in general. If figured, why not put a few on Shadowsfall. They will be under the Deadly Delves label, but we will be finding out if people are interested in the Plane of Shadows.
Also we are expanding class options for the races in the Book of Heroic Races: Advanced Compendium with an upcoming release we are calling Occult Intrigue in the Wilderness, we thought we could include some additional class options for the Shadowsfall races.
As far as setting details, that is more of a longer term project. So we are asking you. Do you want to more Shadowsfall? Are you still interested in it? Please tell us if you want to see a return of the Plane of Shadows as a developed campaign setting.
