This is a HunterxHunter RP plain and simple. This in the timeline of HxH takes place before Gon was born and before Gin was a hunter. Have Fun :p

I welcome you to The Tertaric System(pending)! While this is science-fiction based, it's not completely ships and aliens. While still existing, it's a bit more mixed. A captain would likely also have a sword at his belt for close up fighting, other than his trusty pistol in battle. The peoples and enemies you can meet are vast, so it's best to either find a crew or captain as soon as possible! Good luck.
