Just had an interesting situation i need to clarify.

If you attack with Margaery can you kneel a defender and make them particapte as a defender regardless of the fact that they dont have an intrigue icon ( Rhaegal ), in the same fashion as Tyrion being in challenges and knelt clansmann do not kneel the icon ?

Thanks

You can kneel a character and make them participate as a defender, even if they lack the icon.
