From publisher blurb:
The Nine Counties of Dhavon
The first human lands of Avremier. Nine islands of burgeoning civilization within a wild ocean of green. These are the lands granted to Humanity through the peace of the Winterbind Compact. Supplement I 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 I" for the Avremier old-school edition offers:
A new ranger sub-class - the Wildwalker. Defender of Humanity against the fae.
A new sub-class of thief - the Guttersnipe. A roguish character that survives by wit and opportunity.
Details for running a Cleric in the Avremier setting.
Guidelines and specifics for professional adventuring.
The depths of Infamy to which a character may fall.
Over 40 new and variant monsters, including the unpredictable Seasonal Dragon and annihilistic Negator.
More than 50 items of enchantment to enhance a Player's or Referee's arsenal. Create skeletal servants with the Ring of Bone or turn your own spit into a weapon after chewing some Juju Leaves.
Gazetteer-like listings for each of the Nine Counties of Dhavon.
Deeper looks into the culture and structure of Dhavonish civilization.
