Its a conglomeration of several hive fleets, some old and some new. Your forces would have decimated a good portion of them near the asteroid belt, driving them toward Vigil. I'd say they'd be little over half strength at the current day. I think I may have forgot to mention that the Chaos Armada was forced planetside after Tyranid and Ork fleets practically surrounded the planet. There's just so much going on! Its chaos incarnate! 

Okay, now you're probably thinking "Wow...that's a lot of Tyranids." And thats because, well, it is. Its a lot of Orks too. And while I see Vigil as being bigger than Jupiter, I don't even think that many Tyranids or Orks in one place could land planetside. Therefore, about half of their conflicts will be up in orbit. The situation on Vigil is dire just as players start showing their cards, secrets will be uncovered! 

Will the shattered Imperium manage to fulfill the Lord Admiral's last request?

Will the Tau escape the clutches of the Necrons, and hopefully discover the very thing the Ethereals brought them there for?

Will Kargan and his forces succeed in forging a conduit to Khorne's dominion?!

What is in store for Lord Fel, whom has the temporary luxury of sitting back and viewing the ongoing chaos?

What happened to the Envious One and the Prophet of Ending?! They disappeared!

Will the Passenger succeed in her mission?!

Should we even worry about(or even for!) the Orks?! Or does the Grand Admarul got this in the bag?!

Tune in next time!
