While Zefiro & Friends don't want to fight, they might not get that choice. Having their statblocks should be handy for figuring out saving throws and such.
Notice how extremely fragile all the captives are, because they have no gear -> no armor.For the final fight, the statblocks are spread between the appendix and main text of the scenario. I've managed to get them on a single page, one side per tier.
