The Dead Makou Tree

You may be looking for the settlement of the same name.

The Dead Maku Tree was a Maku Tree, brother of Kasuto, that emigrated to and lived in the land that would become the Land of Famine. His real name has been lost to time, as he sacrificed himself to seal a portal to Termina that spirits were leaking through.

His dead husk now stands in an isolated valley in the mountains to the south of the Old Blin Kingdom. The land started dying after his death, and the spirits that managed to leak through Termina haunt his remains in a sort of twisted irony.
