As the S.S Victoria gathers speed, its pursuers follow suite, weaving through the vacuum of space with terrible patience. The blue flame of the thrusters grows greater and brighter, drawing a trail of blue smoke behind it. In reaction, it seems that the invisible wyverns are putting more distance between them and the ship, as if wary of the flame. Unseen apparitions begin to cluster near the back of the ship in attempts at drawing existence from the Innovatium Engine's exhaust.
The S.S Victoria is not the first space vessel to attempt to traverse the uncharted and perilous Edge, and it surely won't be the last, especially if the vessel returns. Those few who returned, and those fewer who were still coherent, told of their hellish odyssey into the unknown, fending off gibbering aberrations that somehow climbed through the closed windows and evading what the more academic and fanciful have dubbed Dark Matter Wyrms, mighty serpents of negative existence, sea dragon-shaped holes in space-time with predator intent. Biographies of these few explorers have been illicitly published and circulated within esoteric societies across the Imagiverse, where their visions and hints were taken apart and reassembled into still vague but foreboding theories.
During the most harrowing times of their journey, the biographies of spacemen relayed a worrying phenomenon; when the unmade horrors of space were rapping on the doors of the cabins, when the strained moans of the ship were silenced by the roar of the Wyrms, and when the crew was a hair's breadth of unravelling into mutiny and chaos, it was possible to see faint, black, tentacle-like shapes out in space - only visible in the same way that a tired eye could see shapes behind its eyelid - slightly obscuring the stars. During those times, it was easy to believe those were the grasping tendrils of the Unmaker, feeling its way towards the Centre to snuff out the light of the Creators.
Accelerating, it seemed to John, did not improve matters much. The serpents were still on either side of the ship (although, aren't they a little further away than before?) and showed no sign of tiring. Granted, there was no air resistance in the void, but it was still a mystery to John in regards to their locomotion. Perhaps, on a later expedition when he's more accustomed to the Edge's dangers, he might examine these wyrms more closely.
A rattling beside him makes him turn. Another spherical compass, which was previously just limp and pointing downwards, was now shakily pointing in a direction that was just about in front of him. He had heard of worlds tucked into the knots and crannies of the Edge's space-time fabric, almost invisible to the naked eye before it is sucked into a hidden wormhole that acted as a gateway to these worlds. He had a device installed which would point in the direction of a nearby Edge-world, in the same fashion as his Centre-compass. That rattling arrow, to John, pointed in the direction of relative safety. With great care, he pointed his vessel towards the direction of the arrow.
Even as he reached for his horn, the space in front of him began to distort like a disturbed pond. "I have news that is ambiguously good and bad. I've found a world we can hide in, but I have no means of determining what it'll be like. My only hope is that there's land-"
There is a ripping noise, like a sheet of spacetime being torn. The S.S Victoria disappears, leaving two mildly annoyed serpents. They leave to find other prey.
