Malazan

"Anomander Rake's skin was jet black ... but his mane flowed silver. He stood close to seven feet tall. His features were sharp, as if cut from onyx, a slight upward tilt to the large vertical-pupilled eyes.
"A two-handed sword was strapped to Rake's broad back, its silver dragonskull pommel and archaic crosshilt jutting from a wooden scabbard fully six and a half feet long. From the weapon bled power, staining the air like black ink in a pool of water."
