The dotted lines are are rough guestimate of where the plains would end should somebody claim them.
Claimed Lands
Celosia is ruled by Lady Akane. If you want to move in, you're welcome, but I dare you to try and take her land from her.
Eirlys is claimed by Eira in the east and Astina's tribe in the west.
Dalek's territory is also "up for grabs" because he roams in a tribe. His territory can be split up (for instance if you just want the forest island or whatever) and when/if he returns, he may demand a tribute be paid or whatever, etc. Just roleplay with it.
Yurei no Machi (the northern territory) belongs to Maya.
The northern half of the Desert Wastes (jagged ridge) has been claimed by Nicole. The sand dunes in the southern half are still open.
The rest of the territories are unclaimed and multiple areas can be claimed with admin approval.
