The bolt seems to hit just in time to free Ketilvé from the harpy's trance, and bring the creature within range for an attack--not exactly his original goal, but it works.
Dalamus puts his hand crossbow away and uses his strong arm to shield his eyes as he squints in Ketilvé's direction. His injured arm hangs at his side, blood beginning to trickle down the sleeve from where claws had managed to tear through the thick cloth which served as his armor. Dark brows raise and even his ears perk up in interest as magic swirls about the mage's hand.
Even from this distance, Dalamus can see the harpy's face contort unnaturally, eyes and mouth wider than he thought possible as it clutches its head with clawed hands. For a moment, he thought it was going to start plucking out hair and feathers to distract from the psychic anguish, but it seems paralyzed with horror. Its shrill cries pierce the air, a stark contrast to the soft, enchanting song it had been singing just moments ago. Some might have viewed the scene with horror, but Dalamus... A toothy grin spreads across his face as he observes the torment of their enemy.
When at last the harpy can scream no more, its throat ragged and voice wavering, the creature's head rolls back and the rest of its body follows, crumpling into the water with an unceremonious splash, lifeless. A triumphant bark of laughter bursts from Dalamus, cheering on her brutality. "Lolth tlu malla!" Lolth be praised!
His celebration is cut short as movement in his peripheral vision grabs his attention. A harpy on the cliffside near Dalamus has broken away from the pesky crow familiars and is zeroing in on Mirkon, the boy only just now beginning to dazedly pick himself up from the sand. Xsa'ol...
Mirkon lifts himself onto his hands and knees, shaking his aching head. His eyes go wide as a shadow encircles him, slowly growing, and he turns around just in time to see the harpy descending towards him--all sharp talons and powerful wings, like some mockery of an angel. He shrieks and closes his eyes, flinching in anticipation of being snatched--but he is not, and uses the reprieve to scramble out of melee range.
Opening his eyes again, he sees Dalamus using both daggers to block each of the harpy's hands, though one of his arms is clearly weaker than the other. The harpy's wings keep it aloft just above the sand, and it tries to kick with taloned feet--all it would take is one well-aimed kick to disembowel him. Dalamus jumps backwards, and to his surprise, the harpy briefly turns towards Mirkon again, disengaging from Dalamus and turning its back on him.
As swiftly as he can manage while it is distracted by the tantalizing closeness of its desired prey, Dalamus gets behind the creature and jumps to grab the wings' shoulders, dragging the harpy down to the ground, then uses a leg to sweep on of the harpy's legs out and unbalance it. He shoves it forward and kneels on its back as it strains to scrabble and scratch at him and shrieks and buffets with its wings, before finally he pulls its head back and slits its throat. Its limbs flail a little while longer, but quickly lose strength until it stills, its blood coloring the sand crimson.
Dalamus tries to disguise his pants of exertion as he peers up at the young boy leaning back in the sand, huffing and puffing with fear. Him. He is the reason Dalamus is injured and has come close to death in just the last few minutes. Dalamus notes the shining in the little tiefling's eyes, and also the fact that he appears to still be uninjured.
