Hinanbasho sano Mitsu Shimai

Location
The Refuge of the Three Sisters is one of Rokugan's rare shrines dedicated to Lady Moon. Located high in th mountains above the Dragon keeps it sits on the end of a treacherous path called the Climb of the Moon.

The Three Sisters
Those who find the path and survive the trip, find the shrine occupied by three sisters who have tended it for as long as anyone can remember. Common speculation is that the sisters are ghosts, but none can say for certain. The sisters speak in riddles, but will answer any question put to them. Legend has it that the answer will be true, but ruin befalls any who asks.
