Character Name: Itzamaray

Lore:

When she was young, she lived in a house in the middle of a forest with his father, one day her father was sick and she had to travel to find some help, in the road of the forest she found a small cave to pass the night and there she found a sword that she called "Faith".

Next day itzamaray continued crossing the forest and found a town, she started to find some help and the first person that she found was Uther the Lightbringer, she didn't knew who he was but she asked him for some help. Uther heard her history and saw the sword that she found, when uther taked the sword, it became into a yellow sword, both of them didn't know why the sword became into a light sword, the new "Sword of the lighted faith"

When itzamaray took it back, she felt a powerful faith which gave her healing powers. Uther was really impressed about that and then itzamaray thanked him and she ran back to her house to save her father.
When itzamaray returned to her house, the sword radiated a powerfull light and her father got cured.

The years passed, she grew and she heard about the corrupted plague of the lich king, itzamaray left her house to help her people against the plague of the lich king. In a town she got invited by Tirion Fordring to form part of the Argent Crusade .She joined there with a group to travel together to northrend. When they arrived to northrend she was possessed by a voice that said to her that she had to leave her group and travel to another direction, the group tried to speak with her but she rejected them and continued moving away and left them.

5 Days after crossing the grounds of northrend she found a cave where there was the second sword , this time the sword was not in a neutral state, the sword was corrupted by the lich king when lich king found it in the past in a neutral state and when he taked the sword, the sword got converted in a corrupted sword, Arthas the lich king knew this sword and he left the sword in the cave knowing that the owner of the first sword will come for the second sword, the "Sword of the Corrupted Faith"

When itzamaray took the corrupted sword, she lost half of his soul and half of her body became corrupted, half of her is a good person who help and save the people, but half of her is corrupted and her corrupted side can betray to everyone. When the sword of the lighted faith is used to save someone, the sword of the corrupted faith is needed to kill someone and take his soul to balance both forces because the light and the corruption can't coexist togueter. When itzamaray took for first time the corrupted sword, she had to kill so many people to equivalence the power of the two sword because she used the light sword so many years before she found the corrupted sword to save so many people those years.

P.S.
- I know that in terms of lore the light would destroy the other half, but this is a fantasy world, everyting is possible, i could say 1000 things to justify my history, like that both weapons have an enchant that can allow both parts stay togueter etc...
-The English is not my main lenguage, so if there is a misspelling, let me know,
