Deep in the Sands of Itzcala lies a ruin from a long forgotten age. No one alive today can recall its origins, but it is believed to predate even the first War of the Gods and the construction of the fabled ruins of Tewahca.
Tucked away in the Maztica Boxed Set which was written by Douglas Niles and released way back in 1991, there was a small section called “Other Points of Interest.”
In it, there was a brief mention of a little known ruin called Olbi:
"This is a ruin that even predates Tewahca. Though not so spectacular as the latter, it has secrets and mysteries of its own. (Like Tewahca, its location on the map is approximate.) Olbi is a series of caves, the interiors of which show evidence of keen metal tools, or even magical shaping. They are clean and smooth sided, with a variety of stone statues carved right into the floor. These represent the gods of Maztica. The treasures of Olbi are not so numerous as Tewahca’s, but there are many significant examples of pluma, hishna, magical devices, and gold. These are located in concealed places within the ruins — secret passages, buried in tombs, etc. Typically, a treasure cannot be discovered without an equally significant creature or force protecting it."
This book finally brings that ruin to light thirty years after its first mention and all of its secrets are here for your players to discover.
