[@SilverPaw] Healing is just another branch of magic to learn; it's not something that's the purview of the gods. And nor is magic a requirement for the Reonite and Mayonite clergy* or paladins; it's entirely possible to be a priest or paladin with no magical talent at all – the head of the Reonite church in Thaln is a Hundi former paladin and she's completely devoid of magical ability.

The difference between a paladin and your standard priest is that they specifically learn to [i]fight[/i], rather than how best to deal with the temporal or spiritual issues someone might bring to them, or how to run services more, provide guidance, etc. Quite a sizeable chunk of paladins do, in time, retrain and settle down, though.

As a [i]profession,[/i] it rather depends on the nobles, but for the most part they follow your standard noble attitude: the profession of nobility is [i]to be a noble.[/i] Ruling. Administrating. When it comes to it, war. It's not the act of learning magic, it would be making of oneself a mage-for-hire. Being an adventurer, so long as it doesn't interfere with other duties (heirs would definitely be discouraged), is probably a reasonably well-regarded thing to do, like taking part in tournaments and so on… as long as you don't disgrace yourself in the process.

*Caveat, there [i]is[/i] a magic goddess, it probably is for her.
