Beren watched the...thing, burst through the wall and scatter men about like a child kicking over toys. Faintly, he felt his pendant brimming beneath his shirt. He pulled at the silver chain and saw the artifact glowing softly in the gloom, before sliding it back under his top. 

"What was that?" Emmaline asked, the question sounding snippy, though the accompanying look of guilt showed she hadn't meant it as such. Beren had forget he had never shown it to her, other than when they were making out on the couch, and that was not the time he wanted to talk about heirlooms. 

"I'll tell you later, but that means it's... well 'demon' might be a strong word-" 

"DEMON!?" She balked. 

Beren's blessed necklace had been handed down to him from his father, who had consecrated it personally. It had merely been meant as a kind gift from father to son, but it protected him from evil spirits and was very handy in warning when such entities were near. It did the same with demons or anything preternaturally malevolent, but it wasn't useful at categorizing something beyond that. Whatever this thing was, it was made of rain as well as whatever spiritual force that powered it. 

"Just stay here," He told her, leaping out into the rain. It likely looked like foolhardy bravado, but Beren never backed down from a fight if he felt it necessary to engage in it, even if it was against what looked to be sentient water. Immediately the downpour drenched him, flattening his thick head of hair and running down the definition of his muscled arms. Beren reflexively ducked under a flying legionnaire, grabbing at a fallen pilum and tossing it in one, smooth motion at the roiling abomination. 

The throw was perfect. If it had been a creature of flesh and blood, it would have skewered the thing dead center. Even as it flew through the bulk of it, it's iron head sinking into the palisade wall was satisfying to watch. Unfortunately, it was only nice to look at. Suddenly a large blob of water coalesced and swung at Beren, who tried to twist out of the way but was caught and swept into the air. The herculean form of the warrior was sent flying back at the central tower, rolling through the mud. 

"Beren, get in here!" Emmaline cried, desperation in her voice. 

Suddenly there was a keen wailing, and a bolt of lightning streaked across the encampment as men retreated, their shields and spears up, eyes wild with fear. The mad spirit convulsed as it was struck, and a battle-mage strode across the spattered ground in heavy war-boots and an imperial mage cloak over his armor. He whispered another incantation, and a concussive force billowed out like an explosive wave, sending the rain scattering. The men cheered as the monster seemingly disappeared into nothingness, the rain now harmless as it drenched the landscape. 

Beren picked himself up, but he didn't see what happened next, like Emmaline, who had a good vantage point to watch. She observed in awe and horror as the seemingly harmless rain now gathered just above the mage, and as the fellow began another chant, with a mind of its own the water sinuously whipped about and flew straight within the man's moving lips. His words now gurgled and his eyes widened, and men cried out as their camp's magister began to drown from living water, desperately clawing at his face. 

"I command you get in here now!" Emmaline cried to Beren, and while he wasn't entirely used to being told what to do, the need in her voice brought strength to his limbs and he clambered to his feet. 

The mage fell dead to the mud, and the water sought its next prey, slinking around the air like a great serpent. Gradually it became apparent its next target was Beren, or perhaps Emmaline, and it dove towards their position just as Beren stepped back under the archway of the central keep. 

"Beren!" Emmaline screamed, realizing distantly she was yelling his name too much but unable to really find fault in it at the moment. He turned and saw the water arcing towards him, and he moved to grab Emmaline, stepping defensively in front of her with his muscled form and steading himself from the blow that was to come. Fortunately for them, the water crashed against what looked like an invisible barrier just at the foot of the arch, scattering droplets across the floor. 

Beren opened one eye, looking down at Emmaline, then at the spirit that seemed unable to enter. He looked down at his new girlfriend. "Did you do that?"
