Mystikae Eikona is located between Goreme, Cavusin and Zelve in what is now Turkey. In 1220 A.D., Cappadocia was part of the Seljuk Sultanate of Rum. Eventually there will be a map here that will give an idea of the exact location. A modern map of the region undoubtedly will show Nevsehir--the covenant is a bit north and east of that city which was known as NazianzenNyssa in Byzantine times, south of Avanos.

This portion of the wiki contains the notes on such covenant items as vis sources, income sources, boons and hooks, and in time, a copy of the Covenant Sheets.
