Incursion

When a strange, alien, non-sapient species invades Coruscant, Anakin, Obi-Wan, and Ahsoka are sent to investigate rumors of the strange, terrifying incursion. Only, it's not nearly as easy as it sounds when the creatures are not only real, but also, have a hive-mind and are reproducing rapidly in the Underworld. They're dangerous. And deadly. Even against fully trained Jedi.
