Waking up at the crack of dawn for any reason other than to satisfy the needs of the body always leaves Zulii in a black mood. Then again, she's never really a chipper harpy in the first place. Her ears picked up footsteps long before the man actually crested the hill, which put her in the front of the group as she went to investigate the disturbance. The man who appeared only spoke two words.
"Follow me." Normally the commands of other beings didn't carry much weight with her, but the man spoke with unnatural authority, so she obeyed. They marched at a hard pace, but Zulii didn't want to get ahead of them, so she stayed ground side and dogged the heels of the man, all the way to the white tower. It looked very commanding and oppressive to the feral mind of the harpy, cowing her into meekness. That, and she could feel an aura of evil and blackness that far exceeded her own emanating from within. The kind of evil that can only be served, not questioned or disobeyed.
When they entered the Spire proper, the group was informed of something or another, probably something important. Zulii didn't care, nor did she stir when they instructed everyone to change clothes. Moving quickly, the harpy threw on her white robe and tore the back and sleeves off, allowing space for her wings to move about freely. She barely had enough time to grab a mace before a gate on the other side of the room they were in was thrown open, disgorging a host of vicious Gnoll.
Cackling madly, the madwoman took wing, swooping down on the creatures and raining blows left and right. The actual damage she was doing to the creatures wasn't much, but more than one of the creatures met their demise swiping at the airborne harpy. One of the Gnoll, apparently the most clever of the bunch, jumped on the back of one of his fellows and caught Zulii by her leg, dragging the protesting harpy to the dirt. Immediately, she thrust the mace head into the creatures gaping maw and ground her sharp thumb talons into its eyes. She concentrated for a second, then scrambled away from the thrashing monster, which was clawing madly at its wounded face. After a couple of seconds, its head exploded, sending bits of greenish muck onto its fellows, who began howling in pain.
Zulii giggled to herself at the havoc she caused and took wing once more, occasionally dive bombing other wolves and leaving nasty gouges in their pelts and faces with her razor talons.
