More options to consider:
Citadel Mystic (Age of Mortals pg. 30) - Sure, you can no longer cast [Evil], Necromancy or [Death] spells, but you get CHA to 2 saves, a Domain (some of which are rather good), 4 Free Permanently Empowered or Extended spells, and a +6 to CHA checks with Rulers/Nobles/Authority Figures (which may include some of the beings you ask for spells, no?), a d8 HD, 2 Good Saves, 3/4 BAB, and 10/10 Casting!
It's the counterpart to the Dark Pilgrim, it seems. A bit better, in my eyes, as the abilities are much more powerful. Skills are a bit hard to qualify for, though.
It's probably best to delay the Citadel Mystic to higher levels and plan for the spells you'd improve in advance. It's godly powerful at low levels, but you'll later regret the poor low level spell-picks. It can be better than Skypledged, depending on what you plan to accomplish and your level.
