A rather shitty day.

A few miles outside town sat a large barn, doors wide open, within an odd large square metal plate, covering almost the entire floor. Beyond that, a staircase down into some sort of cellar. In this cellar, two humans sit in a well lit room, every surface metal plated, dust and dirt impeccably cleaned and kept out.Several signs adorn the walls, very loudly proclaiming: “NO SMOKING, OR SOURCE OF FLAME.” and “NO OPEN FIRE!” and numerous extinguishers dotted the walls. One wall was made of metallic pegboard, and full up with numerous high-tech looking rifles, pistols, and what looked to be heavier weaponry. The table between them holds a couple maps, 4 empty beer bottles and 2 half filled ones, as well as what looked to be some sort of bizarre chain-gun-like item in several pieces.
“‘Ey, James should be back soon. Wonder how things went with the air god--”
“Elemental lord of air Rob, you know that, get it right. ‘E’s not a god, ‘e can be killed.”
“Right, ‘elemental lord’. ‘Ate dealing with that fucker. Poor bugger, ‘ope ‘e didn’t get chewed out too much fer that slip-up today... Anyway let’s get this ‘water gun’ or whatever it was fixed back up. ‘Ate to not ‘ave it when those fire buggers show up again.”
Sipping occasionally from the beers Rob and Adam began to laboriously put the weapon back together, taking special note that two glowing orbs were fed correctly into what looked like an ammo drum. The lights above them flickered a couple times before going out completely, just before they finished with their task. Red glow-strips along the edged of the floor and ceiling came on.
“Bloody ‘ell. Fucking reactor’s gone an’ died again ‘asn’t it?” Right. I’ll go fix it...” Rob left the room cursing under his breath, grabbing a toolbox next to the door. Cursing, clanging, and various mechanical sounds echoed in from down the hall, before a loud hum started, followed by the return of normal lighting. The hum quickly faded into the background. “Damned orb fell out again. I swear that thing’s more trouble than it’s worth. ‘Free power, Just stick this ever gusting orb in front of a turbine!’ Go an’ shove it up your arse, stupid elemental. Bloody thing’s ‘ard to keep rigged right.” With that, the entire base rumbled and shook, before the lights went out again.
“Shh. Might be the earthies tryin’ somethin’. Grab the sonic vibro-rounds.” Adam whispered urgently, as they made their way quickly to the weapon rack, and grabbed some submachine guns, the ammo magazines were pulsing faintly green. “You get above ground and check if we’ve been breached there, I’ll check down by the reactor and get it going again. Whatever it is, it didn’t trip the perimeter alarms, or the hull integrity sensors. Can’t have a breach down here, not underground, with earth at its strongest!” Adam quickly left the room the way Rob just came, as Rob crossed the room to the stairs that lead to the surface.
Within the smaller reactor room nothing seemed amiss, so Adam quickly pulled a wrench out of his pocket, and had the reactor running in a quarter of the time it took Rob to get it fixed. Bloody idiot’s as likely to break this thing as ‘e is to fix it... Adam thought to himself. He put the wrench away, and picked up the gun again, feeding the magazine into the gun, he grabbed another as he passed by the wall of guns. A second shuddering of the structure prompted a faster speed as he reached the staircase, this time though, the lights stayed lit. The door at the top of the stairs started to bend, the quaking of the structure becoming rhythmic. After 5 or 6 more hits, there was a shriek of metal tearing, and the door flew off its hinges, blasting down the stairs towards him. He lunged to the side, dodging it.
Framed by the large doorway an earth elemental awkwardly stood there, staring down at Adam it breathed in a low gravelly voice, “You have the taint of the air lord. You must be destroyed.” With that it launched itself down the stairs at him. He scrambled to his feet and picking up the submachine gun as he did so, he started firing at the elemental, silently thanking whatever god was listening for making earth elementals so slow. It smashed into the wall at the bottom of the staircase, buckling it outward, it almost separated from its neighboring panels. Adam started to backpedal, and hastily threw the gun onto full-auto, firing with abandon at the beast of stone as it started to pace towards him again, each step shaking the structure heavily. Stone was shaken to dust wherever a bullet hit the thing, and with each step it grew smaller, a substantial trail of dust in its wake. As the magazine emptied Adam’s hope started to dwindle, this was no minor beast sent after them, this elemental was taking quite a beating and not even slowing. He tossed aside the empty magazine, and fumbled for the second one in his pocket, he continued to backpedal towards the door to the reactor. The rumbling and shaking was starting to nock things loose around the room, and with horror, Adam noted some particularly unstable experimental grenades, tottering closer to the edge of their shelf. The elemental paused a moment, and with a leap, tried to close the remaining distance between itself and Adam. As it landed, the room shook anew, and with this final quake, the grenades slipped from their shelf. Time seemed to slow for Adam, as he leaped into the reactor room, sluggishly flying through the air. He slammed into the wall behind him, as the grenades hit the floor. With a concussion that ended his thought temporarily, the elemental was shattered beyond repair.
A few minutes later Adam struggled to his feet and started slowly towards the stairs, quietly praying that there were no other elementals up above. Upon reaching the top of the stairs, a horrific scene unfolded. Rob was mashed against the floor, likely by the fist of the beast that was just destroyed. The VTOL (Vertical Take Off and Landing craft) lay in a mangled and twisted heap on its pad, the barn roof destroyed by its crash landing. The cockpit remained whole, but was smeared with too much blood to hold any life within it. The rest of the craft was long beyond any hope of repair, one of the engines was twisted and wrecked at an awkward angle, the other wing ended in a molten lump. With a tiny squeak of despair, Adam walked out of the barn and towards the city, his mind set on finding the nearest bar and drinking itself into oblivion.
