The Druid Class: Druids are creatures of the forests and the wilds. They commune with nature, trying to be part of it, not separate. They usually have more animal friends then they do humanoid friends, but will brave the more civilized areas of the world if the need is great enough. They prefer more natural armors, so wood and leather, and weapons that deal more with nature and growing things, just as slings, spears, sickles, staves and daggers. They will always have an animal companion, no matter where they are, and if they don't, you can make the conclusion that something bad has happen to their friend.
Look to your game systems class specifics, but here is what I would recommend. They have spells, most dealing with nature, and their spells are based on Wisdom scores, (or the equivalent). They are usually neutral, though lawful neutral and chaotic neutral are very acceptable. They hit almost as well as a fighter and have an animal companion appropriate to your campaign.
