Perhaps you've heard of Winter's Gem, and of the tragic fate of the Lady Karina. And perhaps not. It is, after all, a tale unspeakably old. Yet the Earth does not forget, and those of us who guard it do not wither...
Nine thousand years she has slumbered, while Winter diminished. So obsessed was He in her care, that He allowed Summer to run unchecked. His power dwindled, and Summer grew. There is a great unbalance in the world, young ones. One that I fear will break the back of the Earth itself, if not addressed. Winter must return. It is the Way.
A real-world location fit for filling out your adventure; where norse icelandic fishermen suffered unthinkable conditions throughout frigid winters to harvest the fruits of the ocean.
In the summer there is a small stone jail for those who are caught breaking the rules of the Sorcery Springs Geyser Basin, but in winter they are imprisoned within the warm waters themselves. No bolts or bars are needed, the cold takes the place of prison walls.
(Post zombie apocalypse)-a tribe of humans
Culture: Drumming circles daily around an arena for their bravest brutes to slaughter their accepted foe, the zombie. Feasts of overcooked zombie flesh (to kill all of the zombie virus present). Wooden fortress that make this tribe in the far future look several millennium behind in technology. Instead of becoming a troublesome and unnatural foe that they seek to cure, this tribe has accepted that Zombies will continue to roam their land and, if the undead were to perish (be cured), this tribe would suffer as well.
