Eientei is a mysterious mansion hidden deep in the Bamboo Forest of the Lost. It is built in an old Japanese style, but it does not look old at all for some reason.

When you are at Eientei, it is like time has come to a stop. Eientei is written with Japanese characters meaning House of Eternity―perhaps the name comes from how the mansion makes you feel like the present moment could go on forever.

Nobody knows when the mansion was built. The mansion is a mystery, but so are its residents. Little is known about them.

The Lunar Capital Expo event which was being held until recently gave an opportunity for people to learn more about the mansion. However, the event did not have too many attendees, since very few people could actually find their way to Eientei...

If you are ever sick or injured, you should head to Eientei right away. Unfortunately, it is rather difficult to actually get there, but you should be able to get Mokou or a youkai rabbit to guide you if you let them know your situation.
