"Are they speeding up." Katherine says while, well, trying to move in a zombie-free direction. This is proving difficult, in fact!
She realises that she should most definitely not make any suggestions regarding the use of magic, but under the circumstances of god fucking damn zombie attack there should most definitely be a caveat, and besides, she can always claim diplomatic immunity - maybe. But looking at her other companions, well. That one seems to be wolf a lot, in-between being human, and the other is a mage with a fondness for books and things, and then of course there's Merrick. Yes, this should be okay.
"Two can play that game. A moment please." And she starts humming a little ditty about riding fast into the sunset.
Please enjoy your dose of Time Sphere magic, everyone, it's a nice little speed boost as you get to move through time faster than those around you. Hopefully all the mortals will think they're from the track team.
