Maybe it would be nice to have some sort of demigods, for example elementals (or x creature) that is great in power (magical and raw) and immortal (unless killed) so ppl around there fear it and therefore must sacrifice things or it attacks them or take them rain (if some kind water elemental) or bring snow sooner. But you can gather forces and try to kill it. Some kind of boss encounter idea =).
