The Sentinels as we walked i heard the laughter in the leaves

AW, multiple cameos answering his howl and free form post order welcome as well... maybe someone he hasn't met yet or hasn't interacted with lately?

in the cold night a hush descended and nothing moved save for the slow unfurl of clouds illuminated by a pale and fragile moonlight. even the trees bare in their complexion remained still. the hour crept slowly, the moon rose tiredly, and before long the shadow-shocked world was cast in a silver effulgence. tachyon broke from the cluster of trees that marked the sentinel's zenith -- here he cast back his muzzle and a gentle howl filtered forth into the hyperborean cold. the song reaffirmed his existence -- in the distance it resounded in the copse and informed all within earshot of donnelaith's reinforced claim. the soft croon rose in pitch and fervor until it was a trailing wail and all in the vicinity were reminded of the tenacity a wolf possessed.
