Ok, this is the question: a professional circle of Vherokior working on discovery of things on their land finds a thing dating back to a time when that land was (what later became) Brutor.
Who has jurisdiction over who gets the thing?
Foreigners and Born-in-Darkness: Note that I am not asking who the thing belongs to, though by all means express your opinion on that too, if you like. I am asking who gets to decide. Who has jurisdiction is often a lengthier phase in Matari disputes than the actual court proceedings.
