muse won't be contained any longer

[crypticisms]

Planning to pull an all-nighter? [ sharply ] Good. You don't have time for sleep, anyway; you and I both know you have better things to do with your time, now that you're finally going to take a step in the right direction. You've kept me waiting in the wings too long; it's time for me to spread mine. So get to it. If you expect to keep up with me (laughable as it is) then you have a lot to be getting on with. Like icons, for example. Fifteen won't be enough, and you don't even have that many - though there's nothing wrong with being picky, of course.

Anyway, since my sabbatical is over, how about one for the road?

I'm one step from red, and I'm mostly alone. I beg you in Latin; in shadows I roam. What am I?
