(OOM:
A change of scenery can be nice. Of course, it can also lead to a... Deeper change of scenery.)
The door opens and a massive bipedal... Being walks into Milliways, stopping short as the door slams shut behind him. Okay, this is -not- the garage deck of the Normandy. Faster than one would expect from a being that must weigh well over a ton in that armor, one of his hands reaches to the small of his back and comes back up holding an oblong metal object. Even as he raises it to his face, the thing unfolds with a series of metallic clacks into something that looks unsettlingly like a firearm.
"All right, someone better start explaining the funny business, or I start redecorating the place." The voice is deep, grating, with a hint of a growl. He doesn't raise it, the implicit threat of a Krogan losing his temper is usually much more effective than any shouting. Even for those who don't have the slightest idea what a Krogan is, there is a very palpable sense of menace and potential for physical violence radiating off the figure standing in the doorway.
(OOC: There, Milliways, have your very own Krogan! Physical description and general information on the species is in the userinfo. Open until it falls of the front page, even though It's currently slowtimed for player to get some sleep.)
