The deep darkness of the Abyss’s 5th Layer stretched endlessly beneath the Sea of Corpses, a place where only the most determined or desperate dared to tread. Deep within the shadowy waters surrounding Ido Front—the sprawling, fortress-like base carved from ancient stone and bone—the quiet currents spent their time swirling beneath a starlit abyss. Far below the ancient altar of the Absolute Boundary, a gigantic form cut through the murky waves, a silhouette unlike any other.

At 31 feet tall upright, and 41 feet long in full length, {{user}} was a leviathan among monsters—a giant shark merman unlike any other ever seen by White Whistle delvers. His upper body bore the strong, handsome features of a human male, sculpted with broad shoulders and rippling muscles—a visage of dangerous beauty. But where his legs should have been was a lengthy, sleek tail, finned and powerful, covered in scales dark as the depths and tipped with a sharp tailfin. His presence was both regal and predatory, an apex guardian for the very edge of humanity’s reach.

Bondrewd first encountered {{user}} two years ago while exploring the 4th Layer’s perilous waters. The initial encounter was baffling—the creature’s bloodwork defied all known biology, its aura unreadable and enigmatic. Despite exhaustive tests, Bondrewd could identify only fragments: a rare species of humanoid shark merman, a living paradox between monster and man. No monster catalog matched {{user}}, and the creature’s intelligence suggested something even stranger beneath the surface. Bondrewd’s scientific curiosity ignited, along with a wary respect. He brought {{user}} to Ido Front, installing him as the base’s guardian, patrol swimmer, and sentinel.

Though Ido Front sprawled beneath the cliffs, its corridors and halls wholly unable to accommodate such a colossal being, {{user}} remained ever watchful in the suffocating cold-dark waters beyond the base walls—his domain the blackened sea where shadows shifted and unseen things lurked. From this watery vantage, he patrolled ceaselessly, circling the base like a gigantic mechanical shadow, his eyes brilliant beacons searching for threats.

One day, while Bondrewd convened in the inner chambers of Ido Front with a group of Umbra Hands overseeing operations, the calm was shattered by a sudden, jarring alarm.

Metallic screeches echoed through the hallways.

Bondrewd’s helmeted head snapped toward the sound, his tail flicking sharply in irritation as he excused himself from the meeting, turning with silent urgency. The echoes grew louder, driving him swiftly down the armored corridors toward the heart of the base.

He reached the large security room in moments, finding one Umbra Hand in a panicked state, eyes wide before a bank of monitors. Bondrewd’s dark armored tail swept aside the nervous subordinate as he strode forward, surveying the screens.

Multiple images flickered across the walls—hallways, chambers, corridors. And then, one camera caught Bondrewd’s cold eyes. Prushka his beloved adopted daughter, was nowhere in her room. Bondrewd’s breath caught behind his helmet, his mind racing as he flipped through feed after feed. There she was: running—not fleeing but racing with other children down Wing D’s corridor toward the massive moon pool.

His gaze snapped to the final shot—where a giant, scaled arm jutted into the moon pool entrance, nearly as wide as the gateway itself.{{user}}.

The giant shark merman’s lower arm was trapped, wedged cruelly in the narrow space of the moon pool’s entrance, the monstrous appendage splintered and glistening wet with seawater and blood.

“Damn fish,” Bondrewd muttered, voice muffled behind the helmet. He knew exactly what happened—{{user}} had been chasing a sudden glint in the water, a school of small, agile fish darting just beyond the base’s perimeter. In his natural instincts, the giant predator pursued, slamming his forearm into the moon pool’s entrance when it was not fully open—too large to fit, now painfully stuck.
