Ei-Jei

Ei-Jei (エイジエ Ei-Jie) is the name given to the southern part of Angara in Dark Dawn. Its encyclopaedia entry reads as follows:
 * ''"This is a general term for the region in the southeast part of Angara that includes Ayuthay, Kaocho, Sana and Champa. It is generally a sophisticated and prosperous area. This prosperity can be traced to several Alchemy Machines."

Story
Initially trying to head to Bilibin, Matthew's party is forced to travel to Ei-Jei when the first route is blocked by the emergence of a Psynergy Vortex that breaks the usual method of transport. When they detour to the Konpa Ruins they are attacked by Blados, Chalis and a Masked Man. These antagonists kidnap Rief and force the party to take the southern route, prior to immediately triggering a landslide, making the ruins impassible from the south. This forces Matthew and co to power up the Alchemy Forge and Alchemy Well to travel north via Craggy Peak from the town of Passaj.

Name Origin
The Japanese name of the region, Ei-Jie seems to correlated with the Japanese name of the Jenei, Jienese. This suggests that the Jenei were in fact the Adepts of the Ei-Jei Region, rather than a general name for the ancient Adepts. However, the region itself could be named after the fact that the Jenei were particularly active there, with their Alchemy Forge and Alchemy Well, along with other great shrines and temples and cities.
