I believe it shares the limitations of the detachment it branches off of meaning a primary army of knights couldn't do this.

The lord of war detachment allied freeblades occupy can be filled with units of any faction however, so I think it is possible.

So long as a knight and 8 leviathans are still less than 25% of your army list, lol. It only practically works for gigantic games.

Guess those single-HQ lists are a thing of the past. I bet it's going to be a Praetor, a Centurion and a Consul
