And the House of Rain? Also Khaliks Prime supposedly isn't dead. House of Kings isn't completely demolished, their upper hierarchy are still alive but hiding. There's gonna be at least 1 to 2 battles with a Fallen House sometime, and eventually House of Judgment will unite them all under the leadership of Variks as Kell of Kells. Then they forge an alliance with the Guardians against the Darkness and eventually the Traveller when it is revealed the Traveller is a dick.
