It's Cold Tonight:Taka's(Scar)First Daughter
This is the story of Scar's daughter Artemis from his first love a rouge outland outsider named Cleo, who was Zira's older half sister they shared a father named Cerberus. Cleo's mother was a wanderer named Roho(Ghost) an enchanted lioness that controlled shadows, Cleo inherited this and her father's water finding talent. Zira was born after Roho passed to a prideland lioness called Mbaya(Grim)
This was at a time when Scar was still called Taka. Ahadi and Uru are alive to meet his oldest cub and it is before Scar received his signature scar. This is an alternative backstory of Scar's past, it is inspired by the how did Taka become Scar question. Yes, Scar hooks up with Zira after Cleo dies. Zira adopts her sister's two cubs Artemis and Nuka, who is Scar's only male cub, as her own. Scar and Zira groom the cubs as Scar's scions of his empire.
I am implying Simba and she are in an arranged union. This is akin to a real lion pride ideal, Vianti is born later and mentors her older siblings cubs.
Upon Mufasa and Simba's passing Artemis befriended and mates with an eventually captured lion named Ciel. Ciel's capture by humans becomes a pregnant with her own precious cub Jericho(Using Kovu pics) who is the age of her new sister Vitani. Let's Serafina meets Simba in exhile and have Nala and Liars.
