Ralzakark ruler of Dorastor is or was a mask of Gbaji, he is someone who studied under Nysalor and learned much of his magic, and is also one of Glorantha's most accomplished heroquesters.
What prevents Ralzakark from reconstructing Nysalor/Gbaji in full? Why is his Dorastor still just a shadow of the First Age? With Arkat broken and not seen since the Second Age, and with Arkat's victory further weakened by Sedenya tampering somehow with the Gbaji myth, what prevents Ralzakark from completing the job and creating a new City of Miracles, restoring Dorastor to its former "glory"?
