Editing Hive Fleet Jormungandr (section)

== Arrival and strategies of Jormungandr ==

The first sightings of Hive Fleet Jormungandr were made in the North East area of the Ultima Segmentum. Even though it seemed that it wouldn't cause that much trouble due to its relatively small size (at least compared to [[Hive Fleet Behemoth|Behemoth]] and [[Hive Fleet Kraken|Kraken]] and later [[Hive Fleet Leviathan|Leviathan]]), it quickly grew thanks to attacking unprotected outpost worlds. It spread around the Thalassi Sector, encircling most of the planets within it.

Its strategy was more subtle than the previous two Hive Fleets. Seemingly uninterested in direct attacks at first, Jormungandr floated around space, focusing on throwing as much space debris mixed with [[mycetic spores]] as possible. These spores, containing creatures such as [[Raveners]], [[Trygon]]s, [[Mawloc]]s, and [[genestealers]], managed to enter relatively undetected thanks to all the confusion caused by the massive rain of meteorites and space debris Jormungandr had launched. The infiltrating units then burrowed deep underground and/or started assimilating the population into [[Genestealer Patriarch|genestealer cults]]. The digging tyranids and the genestealer cults would often work together; the mawlocs and trygons would carve deep and complex tunnel systems to protect themselves and to reach more vulnerable spots on the planetary defenses. The genestealers would then guide the digging units to where they should go next and when to start or stop the tunneling operations. This strategy meant terrible news for the planetary authorities, most of which were not only undermanned and under-trained, but also the deep tunnels meant they could never be sure that they had destroyed all of the invasive organisms if detected. Only when the invasion was sure of their tactical superiority would they then call for the Hive Ships to arrive and consume everything.
