For now, though, my main concern was ensuing that when the wyvern-thing pulled forward it did not take the other two Named out of my Night-working. If they left the illusion, our enemy was likely to scatter into every direction: it’d be impossible to stop them from flying over the column then, we just didn’t have the flyers for it. The sun was eating away at the illusion, slowly but surely, but I’d woven it with the personal blessing and attention of the eldest of the Sisters: it’d hold until I no longer needed it.
