Marius smiles hopefully as Zauberei's healing magic revives the others far faster than he could on his own. That smile immediately fades when the burning skulls burst in, however, and he calls out, "Paula, get out and go alert Mr. Evans!"

Finding himself relatively unarmed once again, Marius sizes up these new threats and plays for time by shifting five feet toward the one nearest him and taking a defensive posture, hoping to hinder it from moving further in and harming the evacuees.

Spoiler: Mechanics
Show
Free Action: Urges Paula to get Mr. Evans, on the assumption that Mr. Evans and the staff met her during Marius' stay and in hopes that Evans may be able to summon additional help, if Paula can find a way to communicate with him
Move Action: 5-foot step northwest
Standard Action: total defense
Free Action: knowledge check to identify these new monsters

Possible Immediate Action: If Marius is forced to make a saving throw, he uses Inner Sense to give himself bonus to his save. If Marius is attacked or sees Kendra or a councilmember attacked, he uses Spilled Salt to give a penalty to the attack roll. Marius uses his immediate action at the first opportunity, so whatever triggers it first is what gets affected by the maneuver.
