Those That Came Before - Previous Civilizations on Tenkar's Landing
The island referred to as "Tenkar's Landing", named for it's main commerce and shipping center, was colonized about 200 years ago by the unnamed (and now fallen) empire to the north. There were few indigenous humans, demihumans or humanoids on the island at the time of colonization, and those that were there hadn't established any types of civilization larger than the occasional hamlet or forts built by adventuring types.
There were, however, civilizations that had existed hundreds of years prior.
The first of these was more advanced than the current technology level - think renaissance or possibly even steam punk. They used constructs to dig deep underground and occasionally built above ground, and the remains of the above ground towers and such can be seen in The Ruins of Azagath. What brought an end to them is unknown, but Azagath is a cursed place with craters, leaning towers and mutated creatures roaming the ruins.
The second race would be very similar to Picts, a tribe that came from the far west. They settled the island, mostly avoiding the north, and their burial cairns dot the island. Some conceal the entrance to a single chamber, others are many rooms and many levels deep. Only a handful have been fully explored and many of these cairns are rumored to be trapped or cursed. In some places, the stones no longer mark the entrance to the burial chambers below.
(that should be a decent enough background seed for others to work off of)
