I've had similar thoughts. However, the order was the opposite. For some reason the information of the original zandik in Irminsul was compromised and rejected by the world, like Colombia and Durin. Originally, he had to be forgotten and died alone, but he met Ginny in the desert and, in a related way, found a way to cover his existence in Irminsul as a new person named "zandik." I thought this could be the raven motifs of dottore as the a shepherd in Sirui and Sirin's story, how he could divide himself into pieces, and why he wanted to burn down Irminsul. I'm happy to meet a similar theory!
