There are TWO ‘lost’ Gygax castles crowdfunding right now

Two manuscripts, both unpublished works by Gary Gygax, both featuring castles, are separately hitting crowdfunding sites.

In one hand, there’s the second part of Troll Lord Games’ Castle Zagyg — “This is the second of two crowdfunding campaigns. The first, Castle Zagyg Galleries of the Arch Mage Act 1, was a huge success thanks to this incredible community. At last, we are back with Act 2, which includes all the dungeon levels, maps, and encounters needed to forge your way through the Mad Mage’s labyrinthine castle. These materials have never been published before; we are working tirelessly to produce the complete megadungeon that Gary envisioned.” This one is for the Castles & Crusades game system, and is live now.

Castle Zagyg is a re-imagining of Gary Gygax’s original Castle Greyhawk; Gygax lost the rights to the latter in the 1980s when he left TSR, and partnered with Troll Lord Games years later to produce his definitive version of the castle/dungeon.
