An age ago, before Ionia took that name, a tribe of Dryads called the region home. Inward-looking and deeply spiritual creatures, the Dryads had no interest in the wars that simmered around them, seeking only to be left to their quiet, isolated existence. But the mighty, volatile nations surrounding them could not forever ignore the strategic importance of the land that the tribe inhabited. And so war came to the Dryads.
A fiercely magical race, the Dryads were fully capable of defending themselves against their attackers. But their refusal to advance outside of their lands and bring the invaders low gave their enemy the crucial advantage of time. Eventually, after many years of ever fiercer warfare, a weapon was developed so dreadful that the stalemate would finally be broken.
A brilliant light, brighter than the midday sun, brought a fire more hateful than than the deepest winter. And in the blink of an eye the Dryads, their entire tribe, were gone.
From the smoldering remains came one eternal scream. The suffering of her people made immortal in her agony is all that Thanato is now. A being of endless fury, of unmatched suffering, and the will to set the world to burn.
Thanato is a powerful mage with excellent sustain and deadly area of effect spells.
In the early game, look to pressure your lane opponent with Truefire Smite and Flames of Agony, and hold Pale Step to disengage from any gank attempts.
In teamfights, Thanato's Truefire Smite is a powerful nuke, and her Wail of Despair is an extremely powerful counter-engage, or it can be used from a Pale Step into the enemy back line to send them into disarray.
