Religious event
The Tiefling of the Northern Deserts begin worshiping a being they proclaim will keep them safe during the imminent Great Storm.
One morning, a man awakens claiming that during his sleep he was visited by a young girl he had never seen before, one that was not of their race. He claims this girl told him of the Storms being a test against their resilience, and that to survive the coming blizzards they would need to believe in the woman to keep them safe. Whilst at first the people thought him mad, some began to fall under a similar belief - and over the course of the coming years, a God was born.
