"Wilderlands of High Fantasy is a supplement for fantasy role-playing games published by Judges Guild in 1977. It is part of the same world as their earlier City State of the Invincible Overlord setting materials. "
"Details the wilderness areas of the City State. Valley of the Ancients, Valon, Tarantis, and the Barbarian Altanis. This playing aid includes s 32-page booklet on the villages, populations, leaders, technological levels, citadels and castles, and wilderness monster lairs of these areas. The first of our wilderlands series, this covers the settlements of the City State of the Invincible Overlord, Tegel Manor, Modron, Thunderhold, and Haghill. This Playing Aid has been Created and Approved for use with D&D."
So while everyone is extremely concerned about the mass migration away from G+ social media collapse. I've kept my head down & my mouth shut & I've been going back over some of the Judge's Guild's Wilderlands of High Fantasy By Bill Owen and Bob Bledsaw. I've been looking for a Swiss army knife of sand box & wilderness settings. For me this is the standard of those. The dungeon master is given a thumbnail sketch of a settlement, an alignment, a title or bit about the ruler, & very little basic information.
The dungeon master is fleshing out just about campaign level everything else from the ground up & filling in the blanks as the player play through the adventure location & affairs of the Wilderlands.
