Kasuto (Total War)

Kasuto, more famously known as The Great Deku Tree, was a Sage of Hyrule and the creator of the Kokiri and Koroks.

Etymology
Kasuto is likely derived from the Deku words Kasus (strong, mighty) and Utok (warm, gentle, kind).

Physical Appearance
The Great Deku Tree was a massive member of his own race, the largest on record. With a canopy of leaves nearly ten stories tall, he was one of the largest beings to ever walk Hyrule, only topped by several Druthulidi in ancient times. Though the Great Deku Tree was physically genderless, he assumed a male title after creating the Kokiri.

Powers and Abilities
The Great Deku Tree was given the ability to control the growth and transition of life. He used this power to transform the Kokiri into the Koroks after their ancestors had attempted to destroy the Deku Trees and the Kokiri Forest. Because of his massive size the Great Deku Tree could physically overpower many potential enemies as well as fight entire armies on his own.

Personality
The Great Deku Tree was a very strict and judgmental individual to those outside the Kokiri Forest, though he was seen as a kind and benevolent father figure to the Kokiri. He was often merciful if he deemed a crime small, though he would act with swift retribution if a wrong had been committed.

Ancient Age
When the Kokiri Bandits formed their stronghold in the forests of the Deku Tree, Kasuto lead an assault against the invaders and killed or drove out many of their forces. A group of their children were left behind however, and the Great Deku Tree took pity on them and spared their lives. He brought the children to the heart of the Kokiri Forest, where he set into motion a plan to transform them into creatures of the woods generation after generation. It was then that the Kokiri were established as a small kingdom and the creation of the Koroks began.

The Gerudo Wars
Around the time of 98 AG, just before the Gerudo Wars, the spirit of Sulkaris wandered into the Kokiri Forest and came upon Mido. Mido conversed with Sulkaris and was entertained by the idea of ruling over the entirety of the forests. Mido worked with Sulkaris to set up an invasion of the Deku Tree's Grove. It was the plan of Sulkaris to incapacitate the Great Deku Tree and absorb her Sage powers from him. The attack was unsuccessful and the Kokiri managed to hold the Gohma off, though Saria was killed during the battle and made into a new Sage. For his treachery Mido was banished by Kasuto from the Kokiri Forest.

Sulkaris then opted to outright invade the Kokiri Forest with the entirety of her Gohma forces and absorb the new Sage's powers herself. When asked whom the new Sage of Forest was, Mido lied to Sulkaris and told her that the Great Deku Tree had named Mirora and not Saria the new Sage. During her invasion Sulkaris killed and absorbed Mirora, reconstructing her body and becoming alive again. She did not regain her Sage powers however, and she was swiftly broken and killed by the Great Deku Tree while Saria encased her spirit so that should could not escape. Sulkaris' entrapped spirit was then sealed away in Palagard's Sanctuary, the city of the Huskus, where she is kept under watch by her successor, Palagard.

The Return of Sulkaris
In 160 AG, Lord Akazoo lead an invasion of Gohma through the Kokiri Forest with the intent on attacking Palagard's Sanctuary and freeing Sulkaris. During their march they passed by the Deku Tree's Grove and assaulted the village and the Kokiri. The Great Deku Tree attempted to fight off the Gohma, though Akazoo managed to cripple him and allowed a host of Gohma Queens in infest and lay their eggs inside him. Soon after Kasuto fell ill and began to die, passing his final wish off to Saria: to gather as many Kokiri as she could and complete their transformation in Koroks. After that they were to leave Hyrule forever and find a new land for themselves. His final wish revealed, Kasuto died, leaving Saria with seeds to grow a new generation of Deku Trees with.
