Star Wars: Dark Droids #1 (by Charles Soule, Luke Ross, Alex Sinclair and VC's Travis Lanham) introduces the Scourge, the combined form of the Spark Eternal with ancient technology aboard Amaxine Station. The Scourge seems bent on spreading throughout the galaxy, threatening the Empire and the Rebellion alike. While the event will connect all of Marvel's Star Wars' Original Trilogy era comics, there also are hints that the Scourge's roots may be intertwined with an unexpected foe from the Star Wars: The High Republic subseries: the Drengir.
