I like this idea, especially since I have to run through the "yes, I'm an alien" conversation at least once a month. Which I don't mind! But sometimes it's nice to give people the chance to ask without feeling uncomfortable.
I'm Admiral Tali'Zorah vas Normandy nar Rayya (formerly vas Neema) of the Quarian migrant fleet. Normally I wear a suit, and I still wear it outdoors here, if you've seen anyone in a purple mask that's me. But the same thing that brought us here improved my immune system enough so that I can survive without it, with only minimal allergies. Here, I work in Tech, but back home I was an machinist, hacker and engineer on the SSV Normandy and on Commander Shepard's squad.
Feel free to ask me questions! I'll answer anything and I like talking about ships and mechanics. ... I also tend to ramble if you get me going on about engines. But I do
very good impressions of the Normandy engines.
