Keepers

Keepers are a spiritual class amongst the Elves, not unlike how humans have priests and other clergymen. They are often highly respected in Elvish society as they offer wise counsel and possess the necessary skills and knowledge to communicate with the Spirits of Creation. They are often called upon to care for the sick and wounded, when necessary.
They are often the first to sense a disturbance or alteration in the lands surrounding them, due to their incredible understanding of Nature and the lands and are often Druidic spell casters as a result.
Though usually peaceful, if a situation should occur where their lands are threatened, they are a force to be reckoned with. You can count on a Keeper to lay down his life to get rid of any foreign invader attempting to disturb their natural sanctuaries. Like nature itself, they are usually calm and beautiful, however, like natural disasters, they are capable of laying entire cities to waste, should the need arise.
