Zaestilan moves thru the stone until he is directly underneath the six robed creatures, while he's still within the stone Zaestilan's clicks his fingers and summons his huge sized longsword.
Positioning himself behind the hooded creature which is furthest away from the oily tunnel, Zaestilan reaches out of the stone with his sword in hand and then grabs his weapon with his innate powers of telekinesis.
With a familial ease Zaestilan wields his sword and urges it to attack, all the while watching the affair from the safe confines of the stone floor.
