A hand on the wall, as she gathers energy. She is deep in the hold now, but the walls aren't exactly earth, still tiled over. This is clearly not an accidental fall - not that she had any doubt of that - in fact, the tiles seem specifically made to smooth the walls against climbing out. A particularly sticky Sluagh might manage it...
Her spear in her other hand, braced against the floor, gives her a feeling of solidity in the dark chamber. Chanting, making her bunk for the Whisper, but then the glamour shifts - running through her center, and to her other hand, where the spear is!
A voice she hears, not quite a whisper, but a faint echo, inside her own head. Who would speak to the Mother of all? The feathers on the spear wave as if in an unseen breeze.
