Once the immediate threats in space had been handled, Captain Lattore opened up a channel directly to the Space Wolves' battlebarge. It was only natural that space marine chapters would converse directly with each other, given their history and separate status from mortal forces. Leal had to break the ice before dangerous assumptions might be made.

"Hail esteemed Space Wolf brothers. This is First Captain and Chapter Master Leal Lattore of the Relictors. Our starfort monastery has just entered realspace alongside you. We are escorting the naval fleet of the Imperium Reborn under the new Emperor Amastov..." Leal wasn't sure how the Space Wolves were going to react to all that. He had just identified himself as the core of the previously excommunicated and furthermore declared 'traitor' chapter, The Relictors, and he had flagrantly announced that some mere human, mortal asshole named Amastov had declared himself the new emperor of the Imperium, and they were following him. 

Nonetheless, he went on to deliver the important part of his message, which were his intentions. "We have come in peace and intend to provide you with support in the battle on the lunar surface. Please report to us your status and the status of the forgemoon battle below." 

Leal released the transmitter and waited with one hand behind his back. There was a 50% chance... no, more like an 80% chance the Space Wolves told them to go fuck themselves, a 10% chance they opened fire, and probably a 10% chance they accepted assistance. Nonetheless, Leal would make sure Gregori received the transcript of the communications.
