When I started at C# and included the white keys E and B, I got a much more mysterious sounding scale. This turns out to be C# Dorian. This was one of my favorites, but I overused it so much that I find it a bit tough to take now. Sort of like a favorite spice that you used to put on every dish, until you got sick of it.
Still, Dorian is a very powerful tool when used wisely!
