Ooooo tell me some stuff about your settings! Went back and read up a bit of your writing and the Shoals of the Betweens' Hilatio sounds pretty rad, with the cool fox folks living on a weird cracked desert place
the largest city on Hilatio, Kihalis, has developed an interesting "sport" due to the cracking ground of the Shoal. with enough brute strength, one could allegedly hold the very earth together for a time, to let others escape. this is little more than a tall tale, and yet it has inspired the sport of Riftsealing. contestants drive pitons between two separate stones, and stand astride of them - and then use as much strength and magic as they can to try and tug the massive stones together. whoever gets them closest together wins.
no one has ever gotten them to touch yet.
...oh, and direct terramancy is banned in it for obvious reasons (though it is a far more effective art for sealing the growing rivers of the Betweensea in Hilatio)
