Difference between revisions of "Raysium"

Raysium naturally conducts Investiture, drawing it in from any source. This applies to all of the [[Lights]], but also to spren - allowing someone to transfer spren between gemstones, including spren halves produced during the creation of pairing fabrial.{{book ref|sa4|84}} When using the soul-harvesting dagger, [[Raboniel]] removes the Raysiumraysium strip and reinserts it in the opposite orientation in order to switch the knife from drawing Investiture into its gemstone to sending it back out, suggesting that the Raysiumraysium only conducts Investiture in one direction. It is unclear if all Raysiumraysium is polarized in this fashion or if the portion in the soul-harvesting dagger was specially treated.
