Instruct/ask the Seraphim to work on spreading the word and converting people to the way of Goodness, and to begin work on cities(and/or the necessary infrastructure for cities) that can serve as sanctuary for those who are of Good. Also to help others, through constructing hospitals, orphanages, education centers/monasteries, etc., as well as developing methods to protect and avenge people from that which is evil(aka learn to fight). The monsters would be excellent practice once they start figuring things out. They can ask the followers of Fusil for help; hopefully he will, since it would spread his own sphere and also everyone wants to kill these monsters.
Oh yeah, and try to multiply and stay alive, but that's something you guys were doing anyway, right? Right.
Work on revealing true Goodness to mortals, and basically showing them all the evil that is outside of them(and a bit more subtly, the evil inside them too), and trying to persuade them that the best way to make a difference (and does not everyone want to feel they've made a difference, in the end?) is to work on being Good, and to work on helping others to be Good.
Try to inspire the people helping to fight the monsters to even greater feats of heroism and success(though not stupidity...).
Bless some of the more worthy of my converts as Palats, whom Palatino shall bless with powers that can find, ward off, and destroy evil, as well as powers that can boost them beyond their mortal means.
Find out if the Seraphim have an established church structure or anything yet. Structure is important, even if I don't really care whether it's about worshiping me so much as it is about doing Good and being Good and spreading Good. Good.
((Describing a process of converting people to a religion based around charity and altruism is difficult, although if it worked for Christianity...))
