Well, Severian does see the White Fountain as he breaks out of Apu Punchau's tomb.
Previous to that, Barbatus twice suggests to Severian that he will have access to
the White Fountain power only when its light first reaches Urth. I assume that to
mean the whole Urth, else his power would only work during a certain time of day.
The White Fountain/Claw's power is never fully reliable but I don't get the sense 
the problem is related to Urth's turning.
