What is Modekngei?

Modekgnei is a religion in the nation of Palau. It is celebrated by about 2000 people (about 10% of Palauans) and gained notoriety as an anti-war entity during World War II (Palau was occupied by Japan), although it was around at least since 1915 (and maybe earlier). Not much is known about its teachings as its members are very secretive, but it is polytheistic.
