In the closed circular chamber beneath the underground base, a group of blackish demonic gathered around a stone table covered in ancient runes.
Their clawed fingers delicately traced the intricate symbols etched into the surface as they muttered incantations in a guttural tongue.
One demon, larger and more imposing than the rest, stood at the head of the table, his crimson eyes glowing with an otherworldly intensity. "We must synchronize the coordinates with the underground base in Sector 3 to the Colosseum," he growled, his voice reverberating off the walls.
Another demon, with wings folded against his back, nodded in agreement. "The humans above ground must not suspect our movements. We need to ensure a seamless transition."
