Uh I guess I am Vultor 
 
I am cool with any option the group decides.   
I certainly can take over Lanka after a rollback whatever shape it is in.   As it has been eluded too my time left in this game as Helheim is short.   FYI, you can demolish your own forts.
I am also cool with a rollback and finding another sub or having Lanka stay AI and too the aggressor go the spoils.
