If Ruin were to go to Roshar, then what would it's spren be? I was joking around with my friends when I came up with a spectacular idea. Spikespren. It is like a hamalurgic spike, but instead of being a spike in the Physical Realm, and effecting the person there, it is in the Cognative Realm (it's a spren), and it spikes people and spren there. It would effect the people through the Cognative Realm and if you were to travel to Shadesmar you would see a Spikespren through their flame. Tell me what you think of this amazing theory.
