I couldn't sleep last night and thought I'd feed my brain with the Crescent company motto conundrum (again!). I considered why the moon is a crescent (i.e. shadow over the rest of the moon's spherical shape) and ended up spooking myself with the phrase "Eaten by shadows". We don't want this as a motto!

But the shadow thing is another angle, I suppose.

I'll continue thinking, for what it's worth.
