Get the outside crowd's attention.
"Attention. The [inn name] does not guarantee your bodily safety should you persist in trying to fit too many people inside. Please form an orderly queue and you will be admitted as people leave or are removed. We appreciate your enthusiasm, but request that you bear with us as we deal with this and other issues. Such as the gang warfare you seem so intent in intruding upon. Again, we regret our limited capacity, but we cannot fit all of you in and it would not be very fun at all."
You start broadcasting a message of restraint, decibels at max. This has the effect of numerous people near you clutching their ears, and the tension on the door abates a bit. It attracts their attention your way, too, and not in a pleasant way.
Break out the murder venom, not the pain venom, the fast and messy murder venom.
Then go murder people who arent behaving.
ignore the ones currently killing each other en masse for now, they are making my job easier.
Okay, so I assume you mean the ones outside the wall then. Murder venom is a go. You punctuate the early part of the Eye's speech with spurts of angry hate throgh the slats of the wall. You re rewarded with several screeches of agony, which are then quickly drowned out by the high pitched and voluminous squealing of your team mate, who seems intent on peace via sonic destruction. Unfortunately, this breaks your concentration, and you are forced to cover your sound receptors and hiss, like everyone else near the gates.
If I'm allowed to retroactively cast combat buffs, do so, focusing on strength and toughness agility. If the buffs aren't particularly strong ((roll=<4)), or if I can't retroactively cast them, watch from the roof while enhancing the buffs.
If the giant bug attacks courtyard people, and if I do successfully get strong buffs, enter the fray, seeking to kill or disable (whichever's convenient) all armed combatants. Focus on hit-and-run attacks, not engaging in an extended fight with any individual. Try to focus attacks on whichever gang is stronger, but just attacking someone armed takes precedence over target selection.
If the giant bug doesn't attack courtyard people, let the gangs kill each other. Head inside and kill anyone violent who enters the inn itself.
Assuming my buffs succeeded, follow the giant bug outside, preferably stealthily and ideally while on top of a wall. Watch over the giant bug, and if anyone attacks it, or looks like they're about to attack it, intercept and disable/kill them.
Since we're doing the night all in a go, I assume combat buffs and the like are prepared ahead of the trouble, or in immediate response, so it's all good. our first attempt to buff leaves you a little dizzy and slightly nauseous, so instead of entering the fray, you spend some time above, contemplating life, magic, and the foolishness of whoever thoguht this festival was a good idea. And also fish. fish are yummy. Boy, you could sure go for some fish right now. anyway, after the distraction, you manage to limber up quite nicely, gaining a sort of (sling) bullet-time sense, while your fur stands sharply on end in little spikes that flow along your back and legs like little razors, intermixed with other fur in scale formations.
so the three of you are focused on the enemy at the gate, in good Russian sniper movie fashion, leaving the rival gangs to stab each other and other drunks to their hearts wicked delights. let's see how things progress. Outside, the mobs have stopped trying to break into the inn itself, and are concentrated entirely on getting to you guys, especially the Eye and Cho. This doesn't mean they have stopped banging at the gates, just that they are targeting you instead of the inn. A confused chant is arising within the mob, giving the situation a surreal cast to it.
Inside, the gangs continue merrily stabbing away, and seem to have reduced their own numbers a fair amount. Most of the bystanders have managed to clear the area, so they are fighting in an open ring of sorts.
