The Do'Urden patron and weapon master, Zaknafein, while transformed into a Zin-carla, willingly fell into a pit of acid to prevent himself from murdering his son, Drizzt. In this battle, Guenhwyvar, Drizzt's magical panther, also fell into the same chasm, but, escaping and healing in the Astral Plane, Guenhwyvar made a full recovery.
