Venckman the "shadowy form" casts and a lightning bolt shoots out from the tip of its wing, obviously directed at 60n60e90z. Venckman then continues flying to 55n75e50z heading north.
Michaela, surprised after thinking the thing couldn't move that fast, attempts a get-away..

bring the Protective Aura up as a Free Action before even using Invisibility

SLA Invisibility (cast Defensively so as to avoid AoO) and then

MEA from 20n60e110z to 10n60e10z (inside a fog cloud)

"Michaela, surprised after thinking the thing couldn't move that fast..."
heh heh
Venckman takes the AoO anyway as Michaela flies away. Trip attack (provokes an AoO itself if Michaela is armed). Venckman's following action depends on the results of the trip and the final location of both combatants.
