A war in shadows

After turning Black Canary into one of his shadow thralls, Shadow Thief used her to infiltrate the Justice League Watchtower. Once inside and with Black Canary's info, he went directly to the store room where the league keeps some of the most powerful and dangerous artifacts confiscated.  But to his surprise there was someone inside. Nightshade was inventorying the place when he arrived. Immediately he attacked her before she could react then he decided to turn her into a shadow thrall just like he did with Black Canary. this way there would be no witnesses and he would have another asset within the heroes ranks. And then it was when things turned to worse.

Nighshade powers are linked to the land of Nightshades, and her powers very similar to those of Shadow Thief merged awakening a dark power imprisoned by The Land of Nightshades royal family centuries ago. Now this dark entity was in search for a host and found in Shadow Thief and Nightshade the perfect vessels. Dividing its power so it would be almost impossible to be imprisoned ever again. Now that this darkness walks among mankind. Who else will join it's ranks.
