Rowan slides off his horse as quickly as he can, patting the animal on the side companiably, and begins running toward the cluster of mortals. Maybe there was a way to end this, if not peacefully, then with a the least amount of people dying.
Spoiler: OoC
Going to attempt a fast mount/dismount, which as far as I can tell there is no negative to trying.
Ride check DC 20: (1d20+2)[3]
EDIT: I believe that is a hard no on the fast dismount
If success: double move to N19
If failure: single move to N14
