Small Concepts for the Land of Mountains and Its "Guardian" (Homeland of Aiko’s maternal relatives)

1. Geographical and Economic Overview

The Land of Mountains lies between the Land of Earth (north) and the Land of Wind (south). It is one of several minor nations forming a "trade isthmus" between Earth and Wind, connecting east and west. Due to its small size, its primary income comes from trade and cargo transport. Merchant routes pass through these minor nations instead of their larger neighbors, per pre-Village-era treaties guaranteeing security control over compact territories—and lower transit taxes. 

2. The Chakra Void

The Land of Mountains is the epicenter of "chakra emptiness." Its unique ability to drain chakra to zero causes significant problems for shinobi and summoning animals. In the pre-Village era, it was renowned as the safest region for civilians. Shinobi can only operate near its borders—which is why "Hidden in the Mist Village" was later founded there. 

3. Twin Capitals and Travel Restrictions

The country has two official capitals: "Eastern" and "Western". All foreign travelers must be escorted by Guild members for safety. Movement is strictly permitted along designated routes due to: 

- Threats from the "Five Families" if their territorial borders ("homes") are crossed. 

- Risks of landslides and wild beasts. 

4. Isolation and the Five Families 

With 80% of its land dominated by peaks, gorges, and impassable forests, some clans became radically isolated over centuries. Five major Families rule the primary mountain ranges, each with distinct dialects and customs—but united by shared superstitions. Their territories ("homes") are fiercely guarded. Unauthorized trespassers are captured, and ransoms must be paid to all Family heads, regardless of where the prisoner was taken. (Shinobi ransoms are doubled.)

This "ransom clause" was codified in the trade isthmus treaties to protect local autonomy. Murder of a native results in immediate execution ("blood for blood"). Capitals are notified but take no action. 

5. The Guardian Faith

Mountain-dwellers share one belief: Long before chakra existed, the Guardian watched over its "children" (a status claimed exclusively by the Five Families, inherited through lineage). Legends say the Guardian: 

- Shifted mountains to shield people from outsiders. 

- Controlled weather, winds, and landslides. 

- Demanded annual sacrifices (usually animals or criminals). 

When chakra emerged, the Guardian retreated into the wild peaks to absorb all chakra—granting its people a chance to defend their land without external interference. 

6. The Chakra Void’s Expansion & Yamamori

The Void expands by several kilometers each century. The entity behind it is called: 

- Yamamori ("Mountain Keeper") in myth. 

- Hur'kau by locals. 

- Ekurahashi (its true name). 

No verified depictions exist, relegating it to folklore. Descriptions paint it as a colossal humanoid: 

- Black skin, blood-red circular patterns beneath curved horns. 

- Golden-ribbed torso resembling exposed ribs. 

- Six asymmetrical arms, legs, and a tail. 

- Stone growths tipped in gold from head to tail. 

Rumors claim even a fleck of its gold ensures wealth for eight generations. 

7. Aiko’s Survival

After her mother’s death and Madara’s desertion, a grief-stricken Aiko traveled to her mother’s homeland to scatter her ashes (a local tradition). In a haze, she wandered into the forbidden mountains—where Yamamori is said to sleep. After completing the rites, exhaustion stranded her. As she accepted death, Yamamori appeared. Though angered by intruders, its curiosity (and boredom from centuries of slumber) led it to implant a "fragment" of itself into Aiko. This bond lets it observe the world through her eyes—and prevents her death until it loses interest. 

Post-resurrection, Aiko returned to her village for her daughter’s sake. During the First Shinobi World War, she sent her brothers (Aoki and Aomo) to deliver her daughter (Ayumi) to their great-grandmother in the Land of Mountains, ordering them to stay. After Tobirama’s death, Aiko spiraled into self-destruction, even experimenting with suicide—only for Yamamori to revive her each time.
