I've been wanting to do something like this for a while now. The basic plot I have so far is this: For generations the land of [???] has been plagued with a deadly mist. Humanity survives in small villages scattered throughout the land protected by the Shrines of [???]. These shrines provide a small blanket of magic which prevents the mist from entering the villages. Although their exact mechanisms are not known, it is universal knowledge that they work of what the people call “Shards of [???]”. These crystals, depending on their size, are used as a source of energy for these shrines lasting about two years. To perform this dangerous task, the villages send out a group labeled the “Caravanners” to retrieve shards every two years. They generally consist of those who are more resistant to the mist and even with this genetic advantage, most do not survive the trip. Two ways I thought the plot could go were: 1. This year, the shrines fail to ward off the mist. or 2. Regular journey to find the shards. Keep in mind it's a really rough idea right now, I'd love to hear any feedback! If this gets any traction I'll work on fleshing out an OOC (I'll probably do it even if it doesn't too ho ho).
