Hi! This is my entry in @zenzilla's CC, Counting Stars. I tried to shade and write a story...this took me a few hours...
Story: Xavier (gray tom) was kidnapped as a kit by a rogue group that raised him. They became interested in the Clans, particularly Ravenstar, leader of ShadowClan. They sent Xavier to go on a reconnaissance mission in the Clan. As he went there, he fell in love with Ravenstar's sister, Thymeheart. They became very close until Thymeheart was expecting his kits. Xavier was shocked and remembered his mission. ALTERNATE ENDING ONE When Xavier's group attacked ShadowClan, looking for him, Xavier killed the leader of the group. He proclaimed that he would be joining ShadowClan as Cleargaze. The couple's kits were named Dapplekit, Rosemarykit, and Chaffinchkit. ALTERNATE ENDING TWO Soon after the birth of Dapplekit, Rosemarykit, and Chaffinchkit, Xavier killed the kits and their mother on a moonless night. Skip to either: 3, 4, or 5 3 Ravenstar discovered Xavier's plot. He was exiled and rejoined his group, where he used the intelligence he had collected to slay Ravenstar and take over the Clans. 4 Xavier was never discovered. He stayed in ShadowClan and manipulated Ravenstar into falling in love with him, only until he took all her lives and becoming the new leader of ShadowClan, Bluestar. 5 Xavier was never discovered. He stayed in ShadowClan and fell in love again, this time with Ravenstar. After her kits were born, he ran away. Pick: A or B A Xavier returned a long time later with his group. They attacked Ravenstar, killed her, and took Xavier's kits and raised them. B Xavier returned to the Clan a long time later. He made a life with Ravenstar and he became Cleargaze. After the death of Ravenstar, he became Clearstar and led ShadowClan to defeat his former group.
