She's hiding, right now. Because her father told her to, because Lily is the youngest of his heirs and the only one unable to wield blade or spell in defense of the stronghold. (The countryside has been abandoned, only those peasants lucky enough to squeeze their way in before the gates were barred protected.)
She knows what's coming. Her father didn't bother sheltering her from that. The Dark Lady, the Demon Queen -
(Lily has a knife, but her mother told her it was for herself if she's caught. The Dark Army is not known for kindness nor mercy.)
Lily's hiding in a sheltered room of a sheltered castle, and hating herself for weakness as she feels her people dying and suffering, echoing through the faint currents of the world.
