I humbly present three entries, each pertaining to a different kind of journey.
The first screenshot is of a destroyer fleet I was FCing destroying a Drifter in a C6 Wolf-Rayet wormhole. While traveling with the fleet, many of them first-timers, into a C6 wormhole to tackle some of the hardest content in the game was a journey in itself, the real journey was the story behind this image. This was my first time FCing this kind of fleet, and all scouted wormholes were picked clean the night before, forcing us to try and find a backup. We were dropped on our way through the chain, so we regrouped and tried again. I lost my Confessor when a Drifter chained some wrecking shots on me, but a corpmate graciously volunteered to give me their own Confessor even though we were a long way from home. The image is called "Halo": both for the way the light from the fleet's remote assistance modules and the system's star frames the Confessor in the middle of the shot as the Drifter explodes in the background and for that angel of a corpmate.
The second shot is my Astero, named Stargazer in honor of Katia Sae. The ship's something of a good luck charm: I've had it for years and pull it out whenever I'm about to do particularly dangerous content like Crimson Harvest advanced lowsec sites. This ship's survived bombers, Lokis, and everything in-between too many times to count. Entry's name is "Stargazer," because of course.
The last screenshot is called "Formation." It features four (look closely at the one in the foreground) Leshak battleships flying in perfect formation in a T6 exotic abyssal filament, bathed in residue from another exploding, while firing at a Gila offscreen at just the right angle. Abyssal Leshaks normally starburst away from you in all directions, so it's rare to get this many of them aligned so well together. The "journey" part is both about venturing into the deepest reaches of the abyss, and about the journey it took to work my way up to T6 abyss and be able to do it so comfortably that I can prepare and take screenshots while doing it.
