Balder rushed forward behind Brunnhilde until they separated at the top of the dam, He ran over the curved wall toward the centre of the reservoir, out from beyond the mountainside wall, ignoring the acidic splashes that rose up from the tumultuous waves. The water frayed his leathers, but did little else upon his enchanted skin.
The wyrm continued to thrash, roaring and whipping its serpentine body through the chop, and as it swung a tail through the air toward Balder, he raised his sword to meet it.
He slashed, carving through half a layer of scales before his sword stopped, stuck within its flesh.
The wyrm screeched, the high-pitched cry trembling the mountainside as it wrenched its wounded tail free and spun, its coils reversing in the water as it turned its massive head toward its attacker.
Balder gave a glance at the other side of the dam’s wall, watching as Brunnhilde made her way across to reach the lever.
Just keep it away from your team, he braced himself as the flash of teeth ripped through the air, thrusting up his sword at the jaws.
The blade sank in beneath its chin with a garbled, gurgling roar as fluid filled the thing’s mouth, and the next scream vomited a fresh, concentrated wave of acid over the top of the dam wall and over Balder.
And keep it from damaging the dam, he chastised himself as the stone began to hiss and dissolve beneath the thick blue liquid. His eyes narrowed.
"It’s blood," he recognised, looking into the water of the reservoir with new eyes. The speed of the fresh vitals’ corrosion of the wall confirmed it to him that what they had seen before was the diluted fluid from the wyrm itself, and as the thing rolled, churning up waves, more of the bright, unnatural blue colour clouded in the water, leaking out from its newly wounded tail and mouth. The more it was injured, the worse the water became, and the more it weakened the dam.
Balder threw down his sword, hoping Brunnhilde would have better luck opening the spillway. He had already added to the damage by saturating the water with more corrosive fluid, and the dam on which he stood could only withstand so much of its contents eating their way through.
To the side, Brunnhilde caught the sight of roiling coils rising through the water to meet the small figure of Balder. Her stomach dropped, and the shield-maid’s step almost faltered.
"Don’t stop for anything," he’d said, and cursing, Brunnhilde obeyed.
As she neared the building that housed the lever, Balder cast down his sword, and Brunnhilde almost choked. What Hel-bent crazy thing-
The warrior didn’t allow herself to think any more. Balder must have a plan, and he’d told her to open the spillway.
"Open the spillway," she muttered through her teeth, tearing through the door and all but leaping onto the lever. With strong arms, she yanked it hard, only for it to get stuck half way.
"It’s stuck," Brunnhilde said stupidly to the empty room. "It’s stuck!"
If you cannot cut the thing open, you will have to stop it some other way, Balder’s mind raced. Bludgeon it, choke it, whatever it takes—just keep it from bleeding all over the dam!
The wyrm lashed out, crushing the muscled coils of its tail into a section of the wall Balder stood upon, crumbling the stones into the water and letting the sloshing waves splash out and down the face of the structure.
Or bashing it down, he lamented, glancing over to the spillway station Brunnhilde had reached.
The wyrm circled round, seemingly focused on the activity on the walls now that Balder had attempted to kill it, and as it thrashed around, its tail crashed high above on the side of the surrounding cliffs, sending rocks over the passageway toward the spillway station. “Brunnhilde!” Balder cried out in alarm, halted by the gash within the dam from running back toward her and too far to be effectual. The rocks tumbled downward, impacting with the serviceway path and over the top of the station.
Whatever it takes, he reminded himself as the wyrm turned its head toward him again, blue blood sizzling into the debris within the water reservoir.
The beast made a lunge, full of teeth and toxins, and Balder leapt, diving down from the dam wall and into the corroding water below.
