Karthus

A song is usually the last thing you hear before Karthus finds you, if you hear anything at all.

He is an undying spirit out of the Shadow Isles, and where the living recoil from the thought of an eternity spent as neither alive nor properly dead, Karthus finds nothing but beauty in it. To him, undeath isn’t a curse to escape but a union worth celebrating, and he treats every appearance in the mortal world as an opportunity to share that conviction — usually by bringing death along with him.

Other Shadow Isles wanderers, Kalista among them, carry their own grim purposes through the same fog, but Karthus is less interested in vengeance than in ceremony. He is less a hunter than an apostle, spreading what he considers the joy of death to anyone unlucky enough to be nearby.

Even dying doesn’t stop him. Death Defied, his passive, lets him keep casting spells for a short window after he’s killed, a fittingly literal expression of a spirit who never saw death as an ending. Lay Waste hits an area with delayed, escalating damage that punishes isolated targets, Wall of Pain drags Move Speed and Magic Resist down for anyone who crosses it, and Defile lets him drain energy from nearby enemies while restoring his own mana. His ultimate, Requiem, needs a three-second channel before it strikes every enemy champion on the map at once — a fitting closing note for someone who has never much cared about the boundaries of a single fight, let alone a single life.

He plays as a mage, restricted to mid lane and reliant on mana like nearly every other caster in Runeterra, which makes the rest of his kit feel all the stranger by comparison — a spellcaster whose most defining trait is his continued participation in a fight after being killed in it. Even his song, mentioned only in passing by those who’ve heard it, seems to matter less to him than the silence that follows.
