I've decided to describe my fursona soo:

He is called Silver (it's not his real name) and he is a heroic spirit. Heroic Spirits are spirits of heroes who achieved great deeds in life, having become objects of worship after their deaths (You can read about them here http://typemoon.wikia.com/wiki/Heroic_Spirit). Every heroic spirit have Noble Phantasm, it is something that represent it like magical bow or sword or even a mistical creature(rider). My fursona have 3 Noble Phantasms one is Bow which can shoot 30 arrows in 1 sec. Second are two swords that can destroy every defense and third is lightning which he can use as very powerful arrow or to enchant his weapons or himself (for example he can teleport himself for a short range, make illusions, have speed of light and can feel moves in electromagnetic fields what means that noone can sneak around me because I will sense it) In addition all his weapons are made by his lightning so he can reproduce it with his power (Also I can create wings if I need to fly). While being unstable emotionally becomes a mindless beast with a look simillar to vampire also because of this in sky appears red moon. Moon makes him more powerful (silver light). I also have Mystic Eyes of Charm, well I can't control it. They are casting of a spell that distorts the target's perception so that target sees the caster as someone of great sex appeal (in other words want to have some fun with user of those eyes).

About his true identity and past:

Soo his real name is Byakko (or Bai Hu in chinese). He is one of the Four Symbols of the Chinese constellations and mythological guardian of east. He saw evil on this world so he decided to came here to fight with it. He rescued many people from danger but eventually died in great battle. His only wish was to defend world from every kind of evil and because of this he became a heroic spirit. He took part in one of Holy Grail Wars (It's a war between 7 mages who fight for a Grail which can make 2 wishes become true (one for mage and one for spirit). Mages summons heroic spirit. By doing it mages become Masters and spirits become Servants. Servants have classes like Saber, Lancer, Archer (knight classes), Rider, Caster, Berserker and Assassin. His class is Archer because he could be caster because of his power but he don't like to be called magician and he is very skilled in using swords so he could be Saber but he prefer bow. War ended in draw, partly destroing place where the war was. He stayed in this world for many years (one of his class skill allows him to stay without Master for a short period of time but because of his power he have no time limits). He became lonely and now he hopes to find love (it will be his Master xD)

Personality:

He is kind, cheerful, very friendly and romantic but also shy (he was betrayed by his friends in past so it's hard to him to believe people). He like to swim, sing, play games and have fun with friends (he also like to be teased but shhhh xD). He like sweets very much especially cakes and ice creams ^_^

Tell me what you think about him and if you want to know something else you can ask me ^_^

I've found my master and my love Jason ^^
