Prologue:
Pirate attacks on Tatooine were not uncommon occurrences. So, when a large freighter crashed in the Northern Dune Sea, very few were surprised. Many teams rushed to the site of the crash, not to help the survivors, but to strip the vessel clean of any worthy salvage. The freighter had crashed deep into the loose sand, far from the nearest town, Allon. The first couple of teams to arrive found the ship empty, the crew nowhere to be seen. Even more mysterious was the lack of cargo. The cargo bay was split open but there was no sign of the cargo in the surrounding desert.
Zai Avery had arrived first for once. That was rare for him, he was used to fighting for the best pickings. He had also been prepared for encountering a crew. He had medical supplies aboard his skiff and was hoping that they’d let him leave with some choice components, in return for the medical attention. It looked like the supplies would stay unused for a while longer, however.
The empty ship gave him chills down his spine and his thoughts of salvage had gone out the window. His travelling companions were an informal group of salvagers with which he had an uneasy alliance with. A few members of the group didn’t share his reservations and had started stripping wire from the walls.
Zai took a different route from his group and climbed the sloping floor to the rear of the ship. He passed the cargo bays and paused for a moment. They were ripped apart but, aside from the missing crates and containers, nothing strange stood out. Unable to shake the feeling that he was missing something, he moved up to an observation deck at the rear of the ship. He looked upon the surrounding area.
Wide endless dunes of sand surrounded him. He entertained thoughts that he could see Allon in the distance but knew he was far away from civilisation. He frowned at the shifting sands. "The winds were supposed to be calm today" he muttered. His frown deepened as multiple bands of salvagers arrived. A few were armed, clearly looking to claim the best of the salvage by force.
Zai’s stomach dropped and his eyes widened at what he saw next. The sand moved around the approaching force, in bizarre patterns antithetical of a typical wind-blown dune. The rises dropped away and reformed as the desert came alive. A few noticed, but their cries of panic fell on deaf ears. One group had almost reached the crash site when a large tremor knocked them to the ground. They looked up as large segments coiled around them and a maw, filled the with razor-sharp teeth, snapped down.
The sand-worm stirred the rest of the salvagers into a panic. The majority fled toward the skiffs but two more of the monsters appeared, thrashing out of the sand. Faced with the slaughter, any who made it to a skiff quickly abandoned their comrades. The survivors soon realised there was only one island of safety: the crashed freighter. Those close to the debris managed to board the ship to safety, but there was no hope for those out in the dunes. Zai fought a wave of sickness, and turned away as the worms finished their feast. He sat down, breathing hard and fast. ‘This isn’t happening’ he choked out. ‘This is a nightmare…’
