Lore of the Giant Kings

From publisher blurb:

In the misty prehistory of the Megacontinent of Zul, alien horrors terrorized the nascent mortal races, creating a living Hell on earth. Then came the Giant Kings, mythical god-heroes who overthrew the yoke of the cthonic horrors and ushered in a Golden Age. Lore of the Giant Kings pierces the veil of that distant time, to an era when Giants Walked The Earth of Zul, and a race of demigods taught humans, elves, and other races the earliest forms of magic and science.

Included is a brief history of the Free City of Vadashar, descriptions and advice for incorporating the myths of the Giant Kings into your campaign.
