The ferryman scratches it's bony chin and then without word snatches the abyssal energy crystal and promptly chomps it down from his maw into it's unholy gullet with a gulp! Smacking his teeth together in excited manner he says; "Welcome on aboard lord Tzadkiel, I shall sail us closest point of your desired location." The ferryman makes flourish bow with his skeletal alike frame and once Tzadkiel is on boat the ferryman starts to row his humble looking vessel which should by logic able stand these waters but it does none the less. At first the strokes with the staff and movement of the ship is snail's crawl. But soon the vessel starts speed up faster and faster....soon going faster than Tzadkiel is able to fly full speed but ferryman with casual ease navigates the boat in currents of Stryx, not even single drop of the memory draining waters splashing onto the vessel even if it leaps and pounces around in the still looking river, moved by unseen currents.
