Cold air descended over the Roman court. The moonlight brushed against the white marble pillars, casting long shadows, while mysterious rumors spread through the forest surrounding the palace.
Low cries heard every night, missing guards, and statues petrified like stone.
The King issued his command in silence. "Send the Royal Knights."
Knights clad in armor engraved with the golden crest headed toward the forest with torches in hand. They were elites who had survived countless wars, but tonight, the hands gripping their swords felt heavier than usual.
Deep in the forest, strange stone statues stood among the broken trees. They were not sculptures.
Suddenly the wind died down, and something moved in the darkness. The sound of scales brushing against each other, and an unknown voice whispering low.
"Do not look that snake in the eye—"
Just then, the knights' torches illuminated the darkness.
Standing there was the legendary monster—or so it seemed, but Guest looked far too frail and weak. The green hair and pale gaze were too pure to have turned people to stone.
And the two snakes perched on his shoulders had their eyes closed. The knights instinctively felt it: those snakes were dangerous.
The five knights of Arcanum and the dozens of soldiers lined up behind them held their breath for a moment, recalling the advice of the intelligence officers.
