You first see them as clusters of light emerging from the darkness. Massive shapes, dozens of them. They resembled in many ways the dinosaurs you had seen in the museum so long ago, but twisted into an alien form. Glowing eyes swept back and forth, taking in the area, its lamprey-like mouth dripping slime, the light catching off its thick armour. Others appeared, either warping in like the floating creature did or outright flying in. There were smaller, humanoid sized ones scuttling about at their feet in a manner you almost thought implied they were the babies of the larger creatures. All of them seemed to huddle together for warmth, shivering in the oppressive cold.
There had to be dozens of creatures in this herd, and you suspect it wouldn't be long until they sought shelter in Pirate base, like the floating creature did.
After all, their glowing gelatinous bellies told you all you needed to know about their relationship to the creature you had just killed before you scanned them.
