Sword Fountain: lightning fountain with skeletal birds and a magical sword for Garm.
Voices: just the sounds of children playing with magic before there is a magical accident and crying.
Lizard Lightning: statue with lightning staff used to break boulders (plus the attack of the stone skeletons)
The Tree: test for Dalgar the Dwarf to climb up and over.
Finger beast: attack of a large elf with sharpened fingers for teeth of the 3 elven races.
The statue: Navi finds an emotional clue to her past, a statue of a tiny halfling-like rider upon a fire panther.
Whispers: fight the topiary beasts to get their buckets and fill one with something secret to find a way out.
As the dream was collapsing around them at the well, all the characters make their escape waking up sweating and with the knowledge of the keys. They sever one of Erevan's fingers, fill a bucket with Navi's desire and cast the ritual using the now red rat (all the choices they made during the dream).
Ritual time, the wizard is brought back from his unatural slumber and is now bound to the red rat as a familiar. Dalgar's ritual doesnt go completely to plan though and a dark entity within Erevan passes into the dwarf during the casting. Both the heroes now feel the entity watching them from within, smiling...
