The eldar are an ancient race whose mode of war blends spirituality with a unique mastery of technology. In times of need, their entire race will rouse to war, led by terrifying, almost mythological figures - the phoenix lords, immortal beings that embody the warrior nature of the eldar.
A swift and deadly fighter, Jain Zar can harness the rage of her scream to slaughter any who dare oppose her. When a burgeoning ork empire starts to pose a threat to the eldar peoples, Jain Zar travels to the craftworld Ulthwé to warn them of the danger. However, she finds her plans to divert disaster are opposed by one of the craftworld's own seers, Eldrad.
With so many futures possible, which path should the eldar walk to avert destruction of their craftworlds and put an end to the greenskin menace?
