Build rapport with Sirscus Salamandra and antagonize the rest by appointing him 'group chef' and loudly discussing the cuisine that he will make for the group.
You go on at length about how Sirscus is their official party chef, and about how he'll surely be making all sorts of delicious meals. Like roasted rat on a stick, possibly poisonous mushroom soup, blood and vegetable pie, braised bandit brain souffle, and crimes against man and gods gumbo.
It disturbs you that he doesn't appear to lose his enthusiasm or make any semblance of objections to any of this. The rest of the party looks slightly incredulous and worried, but not quite as much as you'd hope from insinuating that they're going to be cracking open a bandit's skull and feasting upon the goo within.
Prepare a speech about how they must save the kingdom or some nonsense like that. If they ask you anything, respond with the phrase "I'm not entirely sure." Also tell them about the legendary treasures strewn about the kingdom's caves and such, that will keep them busy, and they won't catch on to the fact that there are no legendary treasures.
Prepare a speech? They're standing right there, you don't have time to
prepare a full speech!
Also you're not sure how that last part is supposed to work. Vaguely assure them there's legendary treasures everywhere -> they look for them but never catch on to the fact that there aren't any?
They're stupid and insane, but you don't think they're that
conveniently stupid and insane.
Prepare some insane puzzles to "test their minds" to choose a leader. Also get work started on the next couple "quests".
Being sane yourself, this would be difficult. Also Ngosk is already doing something.
Plus, they're once again right here. You can hardly begin ordering Ngosk to begin working on phony starter quests with them right in front of you.
Vilus speaks up. You repress your sudden rage and desire to have him put to death for daring to speak to you.
Instead, you listen to his insidious speech, from which you gather that he wants to know if there's any demonic portals, necromancer's towers, or other "cool shit" he could get a mount or sword or something from.
Gloria then asks if there's any wizard's towers or other "spell depots" around.
Sirscus asks if you've heard rumors of any legendary chefs he could visit.
The last one asks if you've got a hot daughter, or if there's maybe any female warriors' guilds or something.
