Hi Neo, sorrt but you can't.
When I leave LU ( voluntarily and because I was bored LU since there was nothing else I wanted to conquer or no enemy to fight ) i give to pedigreedjet and to TW clan all my territories, and one thing more, if you try to steal that territories to the TW clan, i will be return to LU, and now without friendship with your clan, and not with Corleone, only like a support for TW, like a sub leader.
Thanks for reading
