Harry Dresden, goes by Dresden. He looks older than he is because of the way he was raised. He prefers to use a sword, a very powerful sword that is named Sabrial. He is a Guardian Angel and Vessel to the ArchAngels.
His sword...Sabrial is the sword of Love, it can cut through anything, yet damage nothing unless to defend the wielder, someone the wielder loves or in the name of love. Anyone it cuts when not used to defend it simply heals their wounds.
Now, can't tell you that because that just ruins all the fun.
