One casts runes in the same way one casts dice, with much the same implications. If you believe in Fate, the runes were fated to land where and how they did. Reading them is reading Fate itself, fully aware of all the pitfalls that go along with that. However, if one does not believe in Fate, but in Luck, then the casting of the runes puts you entirely within Her domain. She may give knowledge and insight, or She may take away hope. The only way to know which is to play.
I lean to the latter view, though maybe talk of Luck takes it too far. Then again, maybe not. There is no reason to anger a divine-like being who might exist. Still, I have never seen any evidence of Fate. Or at least, I have seen no point in believing in It. If Fate exists, our beliefs do not matter. And if It does not exist, why believe at all?
In front of me was a single rune from my casting. A straight vertical line, a rune which cannot be reversed. And yet Isa was always reversed. It represents a freeze in activity, a standstill. It requires letting go of something that prevents progress. It is a lone person, in the cold, trying to drag something too heavy. In order to move forward, in order to get to safety, the burden needs to be released no matter how important it seems.
Unless one enjoys the cold. That is Fate’s problem, It cares not a whit for individuals. It assumes we all want the same things. The cold is my home, and I can move freely in it. Perhaps Luck, if She is real, intended to freeze my pursuers so that I could escape. That is how I chose to understand this casting, at least at that moment.
