This is a truly awesome trifold that almost defines a new genre, the plug and play 3rd party product campaign.  I am super invested in Hull Breach vol 1, and can't wait to see the 1e versions of the trifolds.  I truly think were it not for that awesome project, we would have seen this trifold expanded into a larger collaborative project, because there is so much here, yet it's so simple.  Great work Ian!

Hi Ian! Happy New Year! I was a little bit offline these last days and I haven’t seen the Mega Bundle offer. Do you think it's possible to do an exception and allow me to buy it... a little bit later. Thanks in advance, with best regards. Nefal


Hi Nefal. Unfortunately the bundle doesn't work that way, I can't turn it back on now that it's over.


I already own all the books included in the bundle. Is there any way to purchase The Third Sector besides paying $20?


Hey! For the duration of the bundle at least, we're keeping The Third Sector exclusive to the bundle. After that, we'll consider finding a way to release it for folks like you who already own the included adventures. So, not yet.

Thank you.
