Hey, first time posting here, so if this is a dumb question then I apologize, but why did the desolation start when Chana broke after Shallan killed her? If the weight of the Oathpact was put onto Taln, then why did Chana return to Braize, and then why was she able to begin the desolation by breaking?
My guess here is that her return to Braize was likely what started the desolation, not her breaking. The Oathpact v2 (as opposed to the original or post WaT) was made specifically so that only one could hold it (as the only other viable numbers were 4,10,16 if I remember correctly). Her returning may have restructured the Oathpact into an unstable two-member arrangement that quickly collapsed.
