[Well, here's a new username. It's hard to say if it's a new face, since the poster is clearly taking blood pollution precautions very seriously. Between the scarf wrapped around most of his face and the hat topping things off, the only identifiers are a pair of light golden eyes (potentially concerning, if you've seen a certain recent post) and some stray blond hairs.
He holds the reason for such thorough protection up in a thickly gloved hand. A completely black blood crystal.]
I wish to speak with anyone who is familiar with these crystals and the disease associated with them.
[He pauses before adding:] Do not touch them or breathe around them without protection.
