Mountain Pass, Central Yonshu, Kaidan
After several tries, I finally settled on a hand-drawn, digitally enhanced map of the Pass through the Daitengu Mountains (Tengu King Mountains) in central Yonshu Island, the Empire of Kaidan.
This is 3rd part of the journey for the PC party in the adventure module: The Gift, for my Kaidan: a Japanese Ghost Story setting.
Note the pass to the north is the one where the Daitengu Road uses, while there is a pass to the south. It is now considered haunted and cursed having a ruins of the Oni Shiro - (Demon Warrior Castle), the lower pass is rife with undead, ghosts and demon-spirits.
