Ethereal-Umbra Domain

Aether stood between the two vast and mysterious domains, his eyes fixed on a colossal blue butterfly that fluttered around him with almost ethereal grace.

The creature's vibrant wings shimmered with otherworldly colours, casting an iridescent glow. Aether's mind raced with questions, wondering what in the actual hell was transpiring before him now.

"What are you?" Aether demanded.

However, it did not respond. Instead, it swirled gracefully a few times, its wings creating mesmerizing patterns in the air, before it moved away and began circling his transparent Arcane Card, which hovered in the middle of the domain junction.

Aether felt an unsettling sensation creeping over him, something inherently wrong with this butterfly...

Suddenly,

"Interesting..." a soft, feminine voice erupted from the butterfly's mouth, startling him.
