“It is a sight to behold: like a giant spider web - dozens upon dozens of rope bridges and lines are strung between the hills of the district. And the people. They move along these slender swaying lines as if they were walking down a boulevard.”, The Journal of Mathius Redcap
The extra-planar citadel of Ansern is named after its mage-founder. Ansern discovered the means to traverse the planar gulfs and created the citadel as a haven for his disciples in the art of planar-exploration. The disciples of Ansern continue his work and explore the countless worlds opened up to them by the work of the mage. They are cataloguing everything they discover in preparation for the greatest volume ever written: the Mondopedia, a book detailing many of the worlds. But the countlessness of the planes means that their book will never be finished.
