[EdinSumar]

If you would be willing to exchange War for Protection or Healing I reckon Ilmater (Lawful Good, Triad God) would fit the bill. There are many different Orders for Ilmater Monks, foremost and most prominent amongst those are without doubt "The Broken Ones" whom take it upon themselves to punish those who bring pain upon others and always be there for those hurt or in need, their increadible willpower and fortitude allowing them to survive things which would kill lesser men, without many scratches. Alternatively, there is also the Brotherhood of Crushed Flowers (or something like that) which is all about going to -really- inhospitable places (such as Thay) and then helping anyone they can in these places, healing, protection, assistance. Apart from that, I got nothing.

Remember to give a thought to how you would portray such a Monk/Cleric, such an individual would probably be quite devout, so it is important to understand the deity you are seeking to associate with.
