Siraki

The Siraki are an incredibly advanced alien race, which uses warp technology to make their advanced warriors, they are silicone based and usually build massive town like structures with a massive force field around them. Their ships resemble massive chunks of planets surrounded by massive force fields, though strong against Human weaponry, these ships are dwarfed by Jakeopod ships. Jakeopods can also easily lay eggs in a Siraki and make the larva burst out when it is in the ship. There are around one thousand ships that are infested and under Jakeopod control.
