Recursion is the root of computation since it trades description for time.
Taking a more careful approach Sapphire stands her ground awaiting to see the outcome of her friends' initial attack and also to see if there aren't others lurking who would attack from the rear.
As Thorin courageously moves in for the attack the robed figure fades away until there is no one there, however you can see the faded essence or a ghostly figure pass by you and head into the statue at the center of the village. Sapphire, who is near the statue at the moment can clearly see this and it makes her shiver a bit.
When they get back to where she is standing Sapphire says, "There is probably some kind of mechanism or hidden entrance to something below this statue but how will we find it? Have any of you the skills to find a trap?"
Your initial assessment of the statue and its immediate surroundings does not turn up anything. Perhaps if you applied some kind of Skill it might generate more conclusive results.
Thinking what might be worthwhile to discover any secrets about the statue Thorin applies the skills he knows best for this situation.
