Okay guys. I am creating, and have been trying to create, a sci-fi/fantasy story for a while now. The setting has a mostly sci-fi/futuristic theme, yet weapons such as guns and/or explosives are very rare (as futuristic as my story is). Many soldiers and fighting characters of my story use melee weapons such as swords, knives, etc. I know a lot about swords, but my sci-fi lore is not really all that great. Here are my two questions: How should I go about researching when there is so much information out there? And more importantly, how do I combine the two?
