Hive Splinter Fleet Dagon

The Tyranid Hive Splinter Fleet Dagon has descended upon the Jericho Reach halting the advance of the Orpheus Salient of the Achilus Crusade and devouring every system in its wake.

So far the Imperium has not designated Dagon its own Hive identity but thinks it to be a splinter of another tendril. But already some organisms original only to Dagon have been sighted.
