Set this up around The Darkest Hour, but more specifically during Sasha's visit to ShadowClan in the Tigerstar and Sasha Manga. So Tigerstar and Blackfoot are in charge, with Runningnose and Littlecloud as the medicine cats. Very hard to pick a timeframe in the first arc where ShadowClan isn't having a bad time or half exiled!
I populated this based on who would be in camp right before Into the Wild: with Crookedstar and Oakheart in leadership, Leopardfur training Whitepaw, and Silverstream a newly appointed warrior.
