Roller-coaster

They had legs like the ones of the mythological centaurs. Their arms, there were two pairs of them, were insect-like; in the hands there were four fingers, and in the upper pair of arms the fingers ended in about 7 inch (18 cm) claws.

- Oh.... holy Loooord in Heaven..... - Dan was positively dumbfounded in the face of this 'discovery' . Cold sweat running down his terrified face.

Dan rolled to his left and lifted himself up as quick as he could.
Hastily he scanned in his surroundings for the way out of there and just sprinted away, his body contorted in terror. He couldn't think. He ran in disheartened fashion, not glimpsing properly where he was heading, foggy eyesight and limp knees bothering his flight.
His life was in risk of ending at that time. During all his adult years, his worst fear was having to stick with a meaningless job, that'd only make him waste his days chained into an pointless drudgery, and occupation filled with boring people and not do anything useful.
But, now.....His heart was racing! All his past phobias seemed trivial by comparison. Suffering was, still, merely a meaningless word he couldn't grasp.

As he ran for safety, those 'things' gave chase. And with an outstanding speed. Dan could barely look at those deformed, growling, figures. He was continuously stumbling and tripping on trash bins, poles, stairs and bushes. In doing so, his lab coat gradually began to gain rips, concentrated in the sleeves.
- No.... no !!! Get the hell away from meeee !!
Those things were approaching; and Dan's legs feeling ever so heavy (of all the times!!).
His trembling right hand turned behind and tried to steady a clear line of shot, as he pointed his gun of polymer handle and stainless steel barrel. Grip it tight. Focus. Pulls the trigger. Nothing !! What now? Then he remembered what he had read in the pamphlet about the safety lever.
Quick, he slid it and resumed his hesitating, clumsy targeting. Semi-automatic cocked.

Two rounds blazed out in the night. Moments later, he fired another a third one. One of the monsters crouched heavily, releasing a unnerving screeching sound that was scratching inside, impairing Dan's hearing. The other creature lifted his left arm ominously, making it point forward in a mechanical movement. In the same second, an acute pain in his lower back almost paralyzed Dan.
Close to his left kidney. From that spot, the ailment was climbing his iliac muscles to his upper back trapezius muscles. He felt his ribs contorting and his left side as if forming a concavity; he was definitely feeling disorientated.
And then a strange smell, like rotten onions, nauseating, intoxicating him. Gip was also enveloped in a vague tint of the same odour, as he remained slump....

Look out! An open manhole in the sidewalk right in front of him. He managed to jump over in the last nick of time. Confusion. He was getting stunned; he could swear, now, that he was hearing bells tolling, somewhere nearby. How come? He looked back in despair: the creature was closing in inexorably on him. Take a shot, again. It was what he could do; slow down the inevitable.
Four more shots reverberated in the moonlit night.
"It" didn't even flinch;
Had Dan's unskillful aim missed his target and surely wasting bullets on thin air? It wasn't that dark....!
The other monster had already picked itself up, seemingly undaunted and resuming chase. Impervious to bullets? He had some four more rounds in the chamber. Dan would notice later that these beasts, when hit, shed an odd lemon yellow looking, viscous liquid. The silhouette that hadn't fallen earlier lifted his arm again, pointing it at Dan.

He needed cover. Dan took a left turn and followed through an alley street that crossed the park diagonally. Dan was getting fatigued. No hope. the alley got progressively narrower, jammed, a route full of holes. The straight led into a wide passage way.
He had returned to the very plaza he "and Gip" had been earlier. A signboard they read at the entry, located now to his far left at the plaza's entrance way, spelled «Sahankra of Tumhina».
It was it: 'Sahankra of Tumhina' square. He came there through that side street, and as he stopped, he was facing a moss laden warehouse.
