[Rainman]

To be a Cleric in Netheril, you have to represent your deity if you want their blessings. This means you must cast from within their domains, and you must espouse their ideals by remaining true to their alignment. For every incorrect domain a cleric will suffer 20% spell failure. For every opposing axes of alignment a cleric will suffer 10% spell failure. Not picking a deity at all will cause a cleric to suffer 100% spell failure.
