Ultimate titan

The ultimate titan is a ancient titan that exsisted on a very distant and forgotten land called the kingdom of riven. how it was founded was from 2 people rana and ymir two royals from diffrent lands they were best freinds until rana got ill and was slowly dieing by a unknown diesease ymir gave rana some of his blood in order to save his best freind but not only did ymirs blood save riven it gave her the power of the ultimate titan. When rana woke up her blue eyes were no longer blue they were yellow ymir decided not to tell riven what she was now but because rana had to return to her kingdom 7 years have passed rana was having just any other day until titans came storming in the gates that were open and many people were slaughterd until rana was driven to protect her kingdom and bit here hand lighting struck down and a 900 meter titan looked down on the titans looked at them with a murderous intent that scared the titans runing them back out the gate and soldiers closed the gate backed down the 900 meter titan evaporated until rana was left some citizens saw here as a goddess while some saw here as amonster waiting to attack at any moment. the council disscused aggressively on why it was open when riven soldiers saw a eldia soldier this aggravated rana to feel betrayed (when it wasn't ymirs fault a secret council within the kingdom wanted to take over the kingdom of riven) so rana sent soldiers to attack eldia but were easily killed by ymirs coordinate power then ymir felt betrayed and sent titans and soldiers to attack the kingdom of riven they all busted through the gates rana was informed and sent her 13 year old brother ivan riven (founder of the underground lab t.r.l) to escape with only half of what was the blood (but wasn't complete) while she went to attack back. Rana stepped outside to see the founder titan looking down on her and said "why did you betray me " rana was pissed and said "no you betrayed me!" Rana bit her hand and her 900 meter titan looked down on her picked up the founder titan and threw it ymir was crictly injured but he used every once of his coordinate power and sent 76 wall titans and 800,000 35 meter titans to tackle ranas ultimate titan and eat it but did not let any titan eat her ymir walked away from his critically damaged titan held her injured and immobilized freind and whispered "im sorry" cut of ranas head walked away with the kingdom of riven in ruins. But now her secret descendant who is her (8th generation) great grand nephu who right now has her titan but incomplete, the bone titan (just search titan to see the bone titan i messed up the tittle and i don't know how to change it if you know how, could you please tell me how).

(just so you know why rana did not use any of her titan powers is becaused she still saw ymir as a freind and held back purposely not trying to kill ymir.)
