This is how Razeo learns to wield his Soul Reaver. Cain appeared to him on his 16th birthday.
Razeo: Who are you?
Cain: Lets just say I'm a relative. distant.
Razeo: You seem familiar enough.
Cain: good enough for me child. I see your good with a sword.
Razeo: my mother trained me to be like my father. I practice everyday.
Cain: yes your stumbling proves your quite well with the blade. Im being sarcastic if you can't tell.
Razeo: Jerk.
Cain: no need to be hostile I mean if you want to get killed easily go right ahead.
Razeo drew his sword to Cain but he was not shaken by this.
Cain: oh please if I wanted a fight I would have gone to hell, least demons know how to use a sword.
Razeo looked puzzled by this statement.
Razeo: so what are you doing here.
Cain: It is your birthday isnt it? Ive come to give you a gift.
Razeo: what for? I dont need anything.
Cain: let me put it this way its a gift you already have let me just show you.
Cain waves his hands around until 2 blueish green flames appear before him. Razeo gets into a defensive stance.
Cain: calm yourself boy its not dangerous. This is a manifestation of your soul.
Razeo: my soul? they don't exist.
Cain: oh your one of those. Well I will tell you that they do exist.
Razeo: how do you have it here.
Cain: its a projection of your soul. you see your father had an ability to project black fire from within him. your brother inherited that from him and mastered it.
Razeo: so I will be able to as well?
Cain: no you were born different. I blame your mother. You see you can use something much different from your father or brother and that is 5 times more powerful.
Cain took Razeo's left hand and began to pull energy from him. His arm came to life on its own for a moment until the same flame from cain came out of him but as an energy blade.
Cain: I call it the Soul Reaver, though there are different names for it in different worlds but I like this name. its apart of you and can destroy anything with a touch so do be careful. like you are supposed to train with a sword like its apart of you this is truly apart of you. use it well Razeo.
and just like that he was gone with Razeo staring at this new power of his.
Me: BAKA YOU STALKER!!
