(sorry got the hashtag wrong #KjArtifactRef )
cont: more then his parents did. Sebastion taught him how to be a royal (group name they lived in.) after sebastion raised him for a couple of years he taught him how to throw knives. Sebastion gave him his very own dagger for his 16th birthday and told him to treasure it because he'll be needing it soon. Sebastion told him about all the attention and stuff he could get if he lived with him and this cought castiels attention, he loves attention and being the center of it cont.

at age sixteen he was told by Sebastion to kill his mother and Castiel did so because he hates getting in trouble especially by Sebastion because he is about three times his height (Castiel- four' seven" Sebastion seven' five") and castiel knows what he is capable of. he was congragulated by Sebastion and castiel knew it was wrong to have killed his mother but he had no choice plus he loved being with sebastion, he always felt like a loving father. he was later asked to kill his father with the same dagger cont.

(age seventeen sorry bout that) but he couldn't do it because of his brother hovering over his father so Sebastion killed him instead and told Castiel that he was disappointed in him. After a few years castiel was asked to kill his own brother because he had found out his secret and Castiel gladly excepted but failed yet again due to Artemis's smartness so he killed his true love named Ellie to make sure he would leave a scar on artemis's heart and he did. after a girl named krista moved in Castiel was told to kill her as well, for she will destroy his plans of being leader of the royals. cont.

he failed at killing her and Sebastion was getting restless, not happy with Castiel's misses he told him to fetch a guy named Tyrone, Castiel found him and brought him in and later found out the he is krista's brother. dragged in like castiel Tyrone accepted to trick his sister into coming to Castiels group. but when he sent tyrone out and he brought krista back he surprised him with her group and horrible war broke out, cont.

(ill have to finish tomorrow i've went full blown on this o.o)

Awesome story! What a lovely character! :D

(im back to finish!)
after the horrible war broke out Castiel ran away and Sebastion followed him, after a few days they found a abandoned house where Sebastion and Castiel have been living. Sebastion still teaching Castiel how to throw knives so far he can turn around spot his target and throw it at them and not miss.
(he has a wolf form i will be uploading soon)

more personality traits: has a crazy grin and often grins when he is going to kill someone

weakness: watching his friends be hurt, jumping over a lot of stuff (like jumping over logs every 7 seconds) not good at dodging swords
abilities: very fast, good with knives, great hearing, good at dodging knives and arrows.

completely forgot to do the rp style! whoops! well here it is (using characters from my book so that i know their traits and what not)

rp style: Castiel looked around at the abandoned house, "Sebastion why exactly did you pick THIS place?! Its a dump!" snapped Castiel while moving a sheet off the ground. Sebastion looked over at Castiel and growled low "its the only place we have left be grateful!" As Castiel walked though the house Sebastion found a cellar and went down to see what was inside. Castiel mumbled while checking the kitchen out "this is sick... but our best chance to survive the war... nobody will look here its too beat up" Castiel went back into the tiny living room and poked at the weird animal skin on the floor as Castiel stopped poking the skin and Sebastion came out of the cellar "we have a cellar! we can hide there if theres any problem" Castiel turned around to face Sebastion "great just great, i looked in the kitchen and all it has is a tiny window, and a stove!"

thats accually all im going to do if you want me to do more just tell me! and i just filled my whole comments sections with my own comments lol

Nice job here! His backstory is very complex, and I like his wolf form! :D
