OOC: This is all for Kael, the rest of you are hearing nothing, and are not being guided in the same way.
"I am a prisoner" the voice whispers in Kael's head. Mal whines, and tail tucked between his legs edges backwards out of the door.
"Countless centuries. Trapped! You must free me." The voice is soft, urging, impatient. It is strangely enticing.
Looking at the door you can see no obvious lock, just the four metal bars and then many, many runes. Then, as if guided, your eyes move to the centre of the seven pointed star. There you see a small circlular depression, about the same size as the necklace Jovik took from Nualia's corpse. Inside this small depression is another smaller etching of the star, as if to align with the necklace. This is the lock, the necklace the key. You are sure of it.
"Yes. That is it. I can sense the key. You must do this." The voice pleads.
"I can furnish you with MANY powers. I feel your magic. It is weak, infantile. I can make you a man, gift you with powers far beyond your dreams. Release me and I will show you true magic!"
