So after many dreadful and sweaty (not really) research I have finally found what I was searching for (lol yk 5 minutes). What resembles a railgun most is a gravigun. But as far as I understand they are rare as f***. If that is no problem then I have made the CS. Also you said power level is quite high, and I would also be an Enforcer, so I took the luxury as a Warhammer 40K analphabet to make an equipment set that fits me the best. This means it might be REALLY OP.

[hider=CS]
Name: Robert "DOA" Williams
Race: Human
Gender: Male
Age: 32
Class: Enforcer
Equipment & Weapon: Gravi SMG(on arm), Plasteel Shield (folds into the wristplates), Power Maul, Carapace Armour
Traits: Robert is very strong and quick, but when it comes to converstaion or alcohol he just doesn't know the limits (eg. rude and alcoholist)
Biography: Robert grew up on an avergae hive planet. When he was 16 he joined a crime organisation and managed to get into the higher parts. After someone threw em up he escaped the planet and joined an elite mercenary squad. He fought with them for 10 years, tanking them from damage, the first one to jump into a fight. This is why they nicknamed him DOA. But on one unlucky day, his whole team was murdered and even he could barely escaped. He kept his equipment, and has been doing bounty hunting since.
Appearance Description: Him but more badass (obviously)

Well, if you want to be Homn's handler, then you could easily state that your character is a Rogue Techie. Essentially, they are engineers that don't conform to the Mechanicus' way of thinking. This means they tend to be quite well equipped. Inquisitors tend to hire them due to their lack of belief in the Machine God. Say that he found him on some planet in the ass-end of no-where, but has a strange love for the Emperor so he decided to keep him around.

First thing you need to know about the Imperium, like any fascist regime, they are the biggest fucking hypocrites in the universe. I mean, there entire religion can be summed up as "There is only 1 god that we worship... But there is also another one and they may or may not be the same being" and even the machine worship is "Only human machinery is good, all alien machinery is the evilest thing to ever crawl out of Nurgles asshole." when half of their technology is nicked from alien races, including The Golden Throne that keeps the "Immortal" in Immortal God Emperor.
