Arkhoz concentrated his gaze at the direction of the door and true enough, it is there. There is a wooden door below the island.
However, one thing that made Arkhoz confused was that the door did not look exactly the same door as what Kaora showed to them on the vision. On one of the memories, the door was made of black shining materials.
Also, the one showed to them was not found in the middle of a tree nor an island. The Kaora's door they saw in the vision was standing alone in a wide white stone pedestal while beings of light surrounded it not far away.
"Perhaps an exit door out of this place?" It was Arkhoz's guess.
In order to find out, he must go and open the door himself. However, right now is not the right time. The rest of his crew is currently battling the two white serpents just to shake him off from the power of the divine fruit's temptation. If anything happens to them, it will be his responsibility!
