Here is Egwene's [s]Bankai[/s] Spirit, took longer than expected, caught a bad fever.

[hider=Xosun]
Vessel: Egwene's Vessel is a longsword in its Dormant form. When active, her longsword would glow white, and it will scream and laugh literally. 
After the winter training, her longsword can change into something literally alive and able to extend and bite enemies like a Hydra's neck.

Name: Xosun Gnarledgalls
Title: White Gleam
Gender: Male
Element: Light
Rank: B
Height: 10m , each head is 1m
Weight: The weight of seven swords

Appearance: Xosun is a Four headed Hydra, it gleams silver in colour. Each of its neck move individually, all four of them can stretch to bite their prey. The brown eyes are narrowed, as if its closed all the time. The mouths have four sharp molars. Despite its size, it has thin legs, as if it grew only to support itself inland. Its grey wings are like a sword crossguard, built more to glide than flight. Beware of its deadly bite!

Personality: Xosun the White Gleam has a foul personality despite the holy affinity. Even the notorious owner has quite a disdain to him. He is a wild spirit that is very disobedient. It is very sadistic, preferring to butcher up enemies, and if intelligent, might use its power to keep them alive. 

Powers: 
Healing Bite(s) - Xosun is able to apply healing power to its bites. Unlike Healing Sword, the receiver will feel the bite, and it can be used for torture. It can heal up the the number of heads Xosun have.

Four Swords style - Xosun's necks can be used as blades that cut & slash enemies. Or thrust enemies with bites.
