One thing holds consistent across the numerous worlds of science fiction and fantasy: everyone speaks the same language. Whether it's Lojban, English, Common, or the High Tongue of the Autumn Empire; there's one language that everyone knows, unless plot demands otherwise.
Do not gather and heap up and store for yourselves treasures on earth, where moth and rust and worm consume and destroy, and where thieves break through and steal. Matthew 6:19 KJV
This ring keeps soul in the body even when the wearer is killed, making bringing life back to the wearer much easier. However, if it takes too long, the wearer will begin to rot and become undead. Removing the ring causes the spirit to pass on immediately.
