When Highprince Roion died after being lashed upwards, what happened to his shard blade? Did his body come down eventually or are he and the blade floating in roshar space? Assuming he died of lack of oxygen before leaving the atmosphere, then did blade materialise beside his corpse and fall to land in the shattered plains? Is there just a random shard blade up for grabs in the middle of the shattered plains
