Darth Plagueis

I have this sudden desire to see Darth Plagueis in one of those old-time plague masks.  How could I tell it's him if his entire face is covered?  Because of the highly questionable science experiments he is conducting while practicing his lightsaber forms, that's how.

Maybe I will try to draw this.  Doubt it would turn out very professional-looking, but it might be fun.  Tenebrous scolding Plagueis to pay attention to his lightsaber practice optional (but potentially amusing addition).
