While Lucius sleeps
Darabrac, you slip into a shadow and vanish, keeping a keen eye on the surrounding ruins. There is no sound other than the songbirds and the cool mountain wind. The children soon fall into an exhausted slumber as well.
Your head is heavy with fatigue but you manage to stay awake. After two hours, you hear a high keening cry echo down the valley, through the ruins. Then another.
You peek out from the spruces, and you see a large beast flapping toward the top of the Nexus building on powerful wings. It has a a pair of eagle-heads, birdlike wings, and the tawny muscled body of a lion. It keens again, and Lucius mutters in his sleep. The creature carries a large tangle of branches in its claws.
It vanishes into the top of the building. Birds scatter from the walls, a swarm of sparrows and Wisp. The owl flutters into a nearby pine and hides.
Several minutes later, the beast takes flight once more and wings upward into the valley.
Three more hours pass. At times you doze in the shadows, the heat of the rising sun warming the ruins and your chilled bones. You see some local wildlife, nothing more. The flying beast returns with an even-larger tangle of shrubs and branches, depositing them in the Nexus Room...there is a moment of excitement...but the creature flies off into the valley again.
Two hours later, you are nearly bored stiff. It is past midday. The flying creature returns with a third bundle of brush and sticks and does not leave for nearly an hour.
When it does finally leave, it soars overhead and lets out another pair of keening cries from its beaks. Lucius starts awake as it wings off into the valley again.
(Eight hours.)
Be wary, my friend.
