Unaware of the identity of the entity standing at the other edge of this forsaken world, Arthur gazed at the looming shadow far away and the moving tentacles, his brow raised and his expression indecipherable. The being was talking to him telepathically, its tone wasn't hostile, quite friendly, in fact.
As he heard the first words of Timos, Arthur took a few moments to collect his thoughts before opening his mouth.
"Who might you be, honorable Sir."
At this point in time, Arthur could only feel fear, the shaking of his body, his alert bestial instincts and his unstable Soul, which was trying to distance itself from that massive entity. He couldn't afford to die here, not after all that happened. Lucy and Saly were still out there, in imminent danger and in desperate need of immediate help.
It's rare for him to speak so respectfully to a strange, and a monster, at that yet he did, his back straight and his gaze unwavering, trying to hide his emotions.
