I will declare the rule for operations of this sort.
Let us look at this like chemistry, shall we? Here we have clan A, and clan B.
We take A and B, and mix and heat them until they have reacted and formed substance C. A and B are both gone, leaving nothing behind but C.
In short, when multiple clans fuse, they all die, and create one new clan.
Much like how Fusion was created, the individual clans no longer exist.
Point being, you cannot revive the clan, it is dead. You cannot try to cause mutiny amongst the fused clan, because that is a very rude thing to do. You can argue with me, however, because I'm sure you must have a point somewhere, and it's no use if I never understand it.
