Zenythri Preceptors

The Zenythri Preceptors are a set of stones which can transmit a working knowledge of the Zenythri language, which cannot be learned by a non-native Zenythri speaker in any other way. Since the language relies heavily upon arcane and ancient mathematical knowledge. It is unknown how many stones exist in total, but if five of the stones are placed in the shape of a quincunx, and the proper incantation is performed, the abstract concepts required to understand the language will flood into the mind of whoever stands in the center.

The stones themselves are ancient and are said to resemble small brass spheres with complex asymmetrical patterns engraved in them. It is said that some have gone mad just being in the presence of these stones. They are believed to be scattered across the planes.
