Four Rings

When the Nymlers favor someone, they give genorous gifts. And in this case: Magical rings. The rings posses power. And whoever wears the ring gains that power as long as it's on their finger. Four people, total strangers to one another, were favored by the Nymlers. But what happens when one of them has already received more then one ring and is drunk on power? Possibly even slightly crazy? It's pretty scary to think about.
