From publisher blurb:
The Fallen Lands of Mauvolg
The later human lands of Avremier. Result of an exodus into a region fallen nearly a mile into the ground after a divinely-induced disaster. Bound more by tradition than by Law, the Volgate lands border a number of other realms not always kindly disposed toward Humanity. Supplement II builds upon the information given in Supplement 0 (Avremier) to provide a more in-depth view of this essential region of the campaign setting.
This follow-up "Supplement II" for the Avremier old-school edition offers:
A new monk sub-class - the Kanjin Monk. Heritor of oni philosophies and disciplines.
A new base-class of druid - the Horned/Waiting Druid. Those who honor the Manifestations of Nature above all else.
Details for running a Cleric in the Mauvolg setting.
Guidelines and specifics for the Bucca race.
Exotic weapons and materials, such as iron fans, argent lace, and cloudwood.
Over 40 new and variant monsters, including the alluring Mellified Mummy and the draconic Tyrant Rat.
More than 50 items of enchantment to enhance a Player's or Referee's arsenal. Wield a pair of swift Dragonfly Blades, or explore the watery depths in the colorful Coral Diver.
Gazetteer-like listings for the various regions of Mauvolg.
Deeper looks into the culture and structure of Volgate civilization.
