RedDwarf : there's a crowd forming. grenade time.

...Of your breathing. Inhale. Exhale. Inhale. Exhale. You've driven them back for now, but you saw that crowd forming. No more dumb coffin-stuffers rushing you for the moment. Inhale. Exhale. You control the pace, pull the rhythm back down. Things got intense for a minute, and you lost a bit of your grip in the anti-egregore bloodlust. You can hear them muttering out there, probably planning another attack. But a lot of them are dispersing.

Unfortunately, your grenades were confiscated with your gun. You're making do with shooting anyone who steps foot through the foyer, but that won't last forever.

HeadOfPersonnel : Maybe you can attempt to negotiate with him?
