Editing Setting:Cloudburst/Glasians (section)

====Migration Three====
After the Founding of the Blue Daggers as Chapter 0983 of the Imperial Space Marines, the Glasian invasions continued escalating.  Even as the number of Glasians in each wave increased, however, the composition of space assets seemed almost entirely random.  While the Second Migration consisted of five heavy capital ships and a few Escorts, the Third Migration had only four heavy capital ships and hundreds of smaller vessels that still constituted a roughly ten percent increase in the firepower of the previous.

This time, the Glasians hit the worlds Septiim Tertius, Cognomen, Hangonne, and Delving.  The Glasians were unable to gain much headway against the rapidly-expanding Imperial Navy of the Sector, but they were still able to offload hundreds of thousands of their mutant soldiers on the worlds of Delving, Cognomen, and Septiim Tertius.  The Hangonne defense was purely accidental, as the ship the aliens were using to transport their troops exploded before reaching it.

The Cognomen invasion was a tragic one for the aliens, who were promptly stomped into the dirt by the Legio Congelatio.  The other two invasions were more problematic for the Imperium, as the Daggers did not yet have enough Battle Brothers to defend both Septiim and Delving without heavy aid from mortal soldiery in both systems.  However, the battles were still over in under thirty days, as the Delving Field Guard and Mechanized Toxic Environment Troopers were able to rout the Glasians, who found it difficult to operate their fast, delicate machinery in the corrosive soil and air of Delving.  The Septiim battles were rendered more difficult by the fact that several Glasian ships were able to maneuver into position to fire on the surface, and their unique Ruin Gun plasma weapons had the range to make the hits.  The resultant damage from the plasma weapons being used in atmosphere killed tens of millions of citizens.  However, the Daggers sent a team of teleporting Terminator Techmarines into the huge Control Cylinder over Septiim and destroyed it with powerful explosives, ending the threat.

The Glasian force was eventually overcome, and the Blue Daggers began rapid expansion to their eventual full size.
