## Profile

### Identity

Caster's true identity is **Mercedes**, A blank-faced Homunculus chosen by The Last Spellbook. Mercedes was a Homunculus placed in the care of Queen Diene some years previously, she now joins Ras and Arky on their journies.

Her birth was from an underground Laboratory in Taranor, with an artifical heart used for her creation. The research was conducted by the king of Taranor, and later his son, originally for the purpose of ressurecting the late king's wife. Kayron's influence has caused this research to change it's purpose into conquering Orbis, with this leading to finding a wraith to be a vessel for the revival of the Archdemon Anghraf.

The former knight of Taranor, Krau, had stumbled upon the laboratory and came across the emotionless homunculi, deciding to taking her to the land of Ezera, where she is brought into Tirel Castle and placed in the care of Queen Diene with the request of her former friend. Mercedes had become an advisor to the queen and is indept to her. Though she has faced discrimination from those around her due to her origins as a wraith, recieving faith from a few individuals including the Queen which doubts herself. This changes when she meets with the Heir of Convient, Ras Enclare. She now travels with the Heir and his guardian in journies care after the queen's demise, showing their unbreakable faith in her just as much as the Diene has.

Over time, Mercedes's faith in herself has grown with the trust of her allies and her loyalty to Ras and Arky, developing a great frienship over the time they spent. She would become dependent on protecting them as they did with her, even if it risks her life. Such as when she prevents from the Arbitir Vilred from delievernig a fatal blow to Ras by teleporting both him and herself, and having her soul corrupted by Anghraf. During the battle in Taranor as Ras faces of against Vilred, an emotionless Mercedes impales Arbiter Vilred before absorbing the remaining Archdemon's Might and merging to become a demonic being with the Archdemon itself. Ras defeats the Archdemon, finishing the mosnter with a powerful strike to send her tumbling down hundreds of feet from the Taranor castle, taking Anghraf's soul with her.

After the climatic battle, Mercedes was reduced as an emotionless doll due to Anghraf's corruption, but Ras was able to save her soul by conducting a ritual using the World Tree to remove the Archdemon within her and restore her to her original self.

Mercedes has been absolutely thankful to those who put their trust in her during her journey, as she now acts confident in herself and her capabilities, and strength to protect her allies just as much as they did the same.
