Obsidian Glass-building Technology
The largest mystery in Northern Agia must be the Obsidian tower. For it is one of the tallest towers in Agia, and built seemingly only from Obsidian. How can a tower withstand such harsh conditions such as the weather in the north, and have survived for several centuries is the question that have attracted scholars and priests alike.In Inord in Northern Agia lies a cathedral known as the Obsidian Cathedral. It is completely unique with its tower made out of obsidian. The tower have been dated to around 1877 BGD, and is the only known construction of this kind. No one knows who or why it was built out of obsidian, though there are rumours the high priests of Lesfydd, followers of the goddess Rathias, knows its secrets.
The records written by scholars does not say anything about who built it, while the Lesfydd priests and pilgrim records describe it to be erected in honour of the Goddess Rathias, who in return blessed the building to make it last as long as there were people following her.
