Magical Mystery Trees
Where normal oases grow around sources of natural water, the Purple Oasis is in the middle of a featureless expanse of cold, dry sand. The unique flora here has sprouted from a font of magic. No-one knows what caused it, and explorers can't even agree whether the fertile copse draws from the Push, the Beast, or the Storm.
The leaves glow with a purple shimmer, and bright blue lizards dart around the surrounding sand. It's said that, if you get close enough, you can hear a dull throbbing beat like a heart.
Some say the magic of the oasis charms people so they wander in and never leave. Others say a fearsome beast ensares those who get too close. Others say a friendly Monoduga somehow lives there and offers spiritual guidance to those they deem worthy.
To get to the oasis, you have to wander across miles of cold desert, and the followers of Nachi who often make the pligrimage often do so without packing extra supplies, so their accounts might be taken with a pinch of salt.
