Tenkonto
“In the Far Eastern tongue, Tenkonto means aetheryte. Since ancient times in Hingashi, the construction and maintenance of these devices have been the exclusive domain of the Onishishu, a collective of skilled craftsmen who jealously guard their secrets. As a portal to Kugane, the area is kept under strict surveillance by the Sekiseigumi.

Additional Information
With the game set to Japanese, "aetheryte" is rendered as a foreign word using Katakana: エーテライト (Ēteraito). The plaza's name, 転魂塔 (tenkontō), literally translates to "transport soul tower" which is a rough description of what an Aetheryte does.
