Ako ignored the blue pony's calls from below. Even if she had been inclined to listen she was now too invested in her actions to 'back down', as it were. In the midst of trying to figure out where exactly she could retreat to from her precarious position, her ears caught an improbably set of sounds: birdcalls from species that neither would have resided in this monstrosity of a city, nor near each other.
In moments her old training had come back, the coded signals used to disguise troop dispersal when facing he occasional untrained band of mercenaries or skirmishing with the odd band of ponies from the far south. She frowned at the thought, but was distracted when the calls began again. The message was clear: retreat to higher ground. Second... floor (the usage was odd, but comprehensible), door of green... room?
As much as it might annoy her to take advice from an unseen source with no explanations given, anything seemed better than remaining in her current predicament. And if some fool wished to stage an ambush, a grin curled on her beak, that would give her an excuse to vent some of her frustrations on a worthy target.
Scribble groaned in frustration as the griffoness took to the air without a backward glance, disappearing into the stacks.
'Because this isn't already an impossible enough task we've been set.'"Um, excuse me?" A random pony repeated, for what was probably the third time, not quite touching the blue stallion's shoulder.
Scribble glanced back. "Yes?" He didn't have the energy to startle at the interruption.
"Uh, somepony asked me to give you this note, just now."
The writing pony took the crumpled piece of paper, and then caught the departing pony, "Wait, when did the pony ask you to do that?"
"Just. Now. Like I said."
Scribble shrugged, not bothering to ask for a description he wasn't going to get a straight answer about in any case. Instead he examined the hastily scrawled note:
Please wait five minutes and then proceed to the Green Room (second floor, specializing in world history).
RB
He turned the note over, to make sure there wasn't anything on the other side. "Uh, okay?" Scribble muttered to nopony in particular, only to realize he had the attention of a xeno-changeling and diamond dog. The loud unicorn seemed to have wandered off inexplicably.
