House judgement is an ally of the tower right so they want you to help them become the dominant house sooooo you have to go and kill the house leader on what i would call mini raids there not strikes but there not raids you and a match made fire team optional btw would go to the planet that the fallen kell you want to kill is on europa mercury ect and they are in a playlist and have exclusive weapons like say the house of stone on mercury and you have to kill drakis the feared and he is wearing red armour then the exclusive gun would be red ect
