Yugure Yama

Location
The Twilight Mountains are smaller than Seikitsu sano Yama no Oi and covers the southwestern Crab lands. The mountian range is tough and rocky, littered with Crab defenses. There are many passes through the mountains, but most are garrisoned or booby-trapped.

Travel
The main pass, Kaiu Roka is one of the few ways travellers can arrive in Crab lands unmolested. That is if they have announced their presence to the Crab first.

Falcon Clan
The Twilight Mountains was once the home of the Falcon Clan, but since their near destruction and absorbtion into the Crab Clan it has been in the complete control of the Crab.
