Terrific Elf Relief Shelter- Stabby Plot of Stabbing
Elimnae moves so she's between the elf and the door, drawing the athame and moving her arm up and grinning evilly as the burnt and blackened fingers twitch and move, "Oh, it's too late for my soul. I'd be more worried about yours." She motions with the dagger, her own life-magic gathering and collecting as she attempts to bind the elf with vines and plants she's growing from the living wood of the tree-hut, including a gag in the bindings.
If that works, she's going to stab the elf in the belly, angling the blade up, aiming to pierce the heart from beneath the ribs.
