Solus Sage

"Yes.. Yes! your crimson blood! how it beautifully resembles my own crimson hair! let me see more of it! let it rain scarlet from the heavens above, tainting the skies and changing it into a lustful carmine! a wish I so badly need granted! allow me to drink from your fountain of garnet! to taste the traces of iron in your own ichor!"

Solus Sage is the uncle of Theodore, Silas, and Ashiel Sage. Following the death of his brother-in-law, Erza, Solus was given the responsibility of taking care of his three nephews. Solus was a gun for hire, and he still hadn't give up the job although he had new duties. This led to Ashiel mainly being the one responsible for them, however Solus was acquiring large amounts of money for his missions. With this money, he would invest in a larger home for the four of them. By the time they were in their mid-teens, they moved from the house, and began a life of their own, while Solus returned to his original profession.

Personality
Solus, simply put, is a sadistic man. He enjoys his profession (Killing others) and becomes very offended when someone threatens his labor. He seems calm and collected around his nephews, wanting to lead an example, but while on his missions or when fighting, a side of him is revealed that he has never shown to anyone before. This side shows the sadist in him, the true blood-craving, belligerent, man he is. Solene referred to him as "a beast, mad with rage". His sadism could be a result of his father's abusive nature, having persecuted him because of his Potential blood.
