Well as designers of Dream-cards we often come up with cards that create new situations. A card that allows a character and his followers to face an attack as if they were a separate company, for example.
Yes one could use the same spacial system for indicating followers as one would normally, but if you've ever played a 20 Dwarf Unexpected Party company, you'd know that becomes tricky, the table isn't big enough. Often the 1-2 minders are simply all placed to the side, as "they don't cost influence to control" anyway". But turns out they must still be controlled, so good to know.
@body modification. Thanks for clarifying, though indeed it is not clear

. Well does the prowess-modification rule with respect to items (i.e. weapons etc) apply outside of strike sequence? Then the "similarly" would imply this also applies to body modifications.
