✟ Backtagging: Yes please.
✟ Threadhopping: Yes.
✟ Fourthwalling: Yes.
✟ Offensive subjects (elaborate): BAHAHAHAHA NO. Do whatever, Garvi's seen it all.
✟ Hugging this character: Yes, expect confusion
✟ Kissing this character: Yes, but expect more confusion
✟ Flirting with this character: Yes, but expect him not to notice.
✟ Fighting with this character: Yes. He's a space marine. If you're not fighting him, you're doing it wrong.
✟ Injuring this character (include limits and severity): Yes. He's a space marine, if he's not getting awesome bodily injuries, we're doing it wrong :D
✟ Killing this character: Good luck! But sure if it happens, let's discuss it in detail
✟ Using telepathy/mind reading abilities on this character: He's straight up and down, and open to that sort of thing. He's really fairly resistant to mind control, though.
✟ Warnings: ... this character is from Warhammer 40k/The Horus heresy. He is an extreme secular humanist, he has been taught to fight and oppose sorcery, aliens, demons, uncontrolled psykers. That being said he is a reasonable man, so his chances of randomly aggroing on you are fairly low.
