Lilaethan means Maiden World in the Aeldari Lexicon. These worlds were originally chosen and terraformed to be paradise worlds by the ancient Aeldari at the height of their interstellar empire long before The Fall, and subsequently the birth of She who Thirsts, tore their realm apart and fractured the survivors of their race. It is on one such world that our story takes place.

Yonah, a small Maiden World with a fierce (but relatively few in number) Exodite population, has recently been seen by the Farseers of multiple Craftworlds. The Skeins of Fate show a grand threat to the planet, which will soon be beset by multiple enemies. The complex threads of possibility have seemed to coalesce over this tiny planet for reasons unknown. Yet, such dire warnings cannot be ignored. With the help of the Harlequins, an ancient and massive Webway Gate on Yonah's surface has been reactivated, and the psychic call for aid has gone out. Who will answer said call, and what terrible enemies are set against them? Perhaps more importantly; why Yonah? What ancient eldritch secret does this Maiden World hold that causes the Seer Councils and the Harlequins to be drawn to its defense? None yet know the answers; but of one thing we can be sure... the peace and balance of this paradise world will soon be shattered, for in the grim darkness of the far future, there is only war.
