Why did the Akaviri Potentate relocate the Imperial court to Elsweyr?

I’m curious as to whether anyone else has speculated as to the motives of Versidue-Shaie in moving his seat of power so far south to Senchal.

Such an act was no easy feat without doubt, even just considering the logistics and expense. Not to mention the socio-political considerations; the Imperial City is not just in effect the central point of power that disseminates throughout the empire, it is an intrinsic essential facet of Cyrodiilic cultural identity. It is more than the preeminent metropolis, it is a sacred symbol of the ideals of Imperial Cyrod.

Did the first ruling potentate make a bold tactical decision or was he forced to flee? Were the ruling classes in the South more loyal or were they weaker and easier to control? Were factions north of Cyrodiil more hostile? Was it Versidue-Shaie’s intention to lessen the traditional influence of the Nibenese battlmages and Colovian warrior-kings? Is the reason metaphysical or magical? And of course there is the most important question to ask: “Why Elsweyr?”
