The landscape around Mount Iki is notoriously treacherous. Massive chasms, large mountains, and incredibly dangerous wildlife surround the mountain. A large portion of the Nii'gata that do manage to survive their rite of passage and begin to travel to the mountain's peak never make it, further thinning out the already small number of survivors that learn from Taiyu.
The mountain itself is massive and towers over all those around it. At the very top sits a large compound made entirely from stone and clay, carved into the side of the mountain. The compound is where the aspiring carrier trains with Taiyu. Further up on the mountain sits another building that towers above the clouds and is almost always illuminated by the sun. This building is where the pure blooded Nii'gata meditates for weeks on end to unlock the Ryū no iki.
Wall of Ancestors
The Wall of Ancestors resides at the top of Mount Iki. The Wall of Ancestors is a massive circular cave with a single large stone gauntlet in the middle. The far wall is only ever lit by the open entrance of the cave at a certain time of day, but when the light hits the far wall, it reveals thousands of bloodied hand prints. Each Nii'gata that passes their rite of passage and completes Taiyu's training regime to learn how to use the Kekkei Genkai are allowed to add their blood and hand print to the wall. There are four distinct hand prints on the wall where no other hand print is present. The one at the very top, far out of reach, is Tatsuo's. The three below him, in order from oldest to youngest, belong to Hisashi, Katsuro, and Susumu.
