With the advent of fusion drives, the first large colonizer ships began to appear. The Venture II was one of them & of a handful to be lost without any trace.
Found over a century later, the inhabitants of the ship had succumbed to the effects of a dormant magnetar that became active as the ship neared, its radiation shielding of that era was insufficient to protect them from the intense gamma, x-ray & magnetic forces of the little known stellar monster.
Tidbits: Ship is not a 3d render, all Photoshopped found details and hand-drawn lines etc. Engines are pics of F1s used in the Saturn V rocket. Here's a peep at my process:[link]
