Lesser vampiric trait.

So for me: there's very little stopping you right now from being a vampire. Just act up the bits that aren't against the rules: Wear a lot of black. Describe having fangs. Remember that as part of "you want to keep your job at nanotransen" you generally even as a vampire would want to keep that quiet: so you wouldn't walk around with (I am a vampire) nametags and complain when medbay won't give you blood bags. You'd play it sneaky, cool. Work a shift of QM and order yourself a spare bag to enjoy. Slyly ask the bartender for a "really" bloody mary and emote being mildly disappointed when it isn't bloody. Wince and hiss if someone takes your photo. But, and this is clear: Don't do things antag vampires would do, and don't tell the organisation that hires humans you aren't human. Roleplay it out, maybe with a crewmember you get to know you drop hints

Tried playing the character as just is canonically a vampire with no mechanical impact and got told off by several admins when I mentioned it in the discord so fuckin thanks I guess.
I actually hate being told off over a character I enjoy too much to be comfortable with just ditching or fundamentally changing to the point where it wouldn't be the same character.
Just to clarify I don't mean I hate this in like an angry way I mean like it actually brought me to tears. I get emotionally attached to characters I enjoy and it feels like hell to be told off about it.
