"Forest Canopy" is a specter — a ghost formed from the energy of the deceased Forest Canopy, who still retains her memories. The specter is the final boss of chapter 2. Forest Canopy is evil and single-mindedly wants to 'pass on', and do whatever is needed to do that. Eventually, the heroes manage to cast a healing spell on her, getting her back alive.

I will likely edit your voice with reverb effects afterwards to give it the feel of an insubstantial creature.
