You recall when your were younger the luscious landscape that you grew  up in, watering holes and vegetation would litter the areas that it could grow in, wildlife was abundant and tribes of wandering herds of different species could be found across the country of vestra. You remember watching as everything around you died out. First it was the vegetation, slowly at first, then quicker and quicker, next the water went, your tribe had to move farther much more quickly to stay near water and vegetation, the water itself became poisonous, you recall diseases passing though the tribe attributed to the water, the old and the young died off because of it, your people were nomads no more, your tribe disbanded and  spread to where they were welcome they tended to find themselves in the southern cities of vestra as that is where most travelers went to and were welcomed.
You spent many years traveling this continent, now it's a wasteland. You have based your life around nature and the respect of its dangers as well as its beauties, you have found great beings that took pity on you, as well as earned their respect. They bestowed upon you the ability to transform into the giant horned toad. They also gave you a token of their gratitude before they left you to your own journey and adventure and sent you on your way.
It's been many years since then, and you haven't forgotten what you have learned or what was said, you have watched as all the nature and life have left this land, the ground itself seems hostile to you, and you cannot bear to even sleep on it or walk barefoot on it anymore. You return to your parents in harth, hoping to maybe find the answers to what is going on in this land, you try to stop at the last watering hole you know that remains as you approach you notice a group of men dressed in green cloaks, not many, no more than 5-6. You know that people try to claim the watering hole and its riches, you however believe that natures bounty should be available to everyone. These men in green cloaks do not appear to be trying to keep it for themselves or be threatening, they just sit around their fire and laugh and play music, you were considering heading down there when you hear a scream from the camp, you look over and see the camp being swarmed by men lightly dressed in red killing everyone nearby, the screams stop and it becomes quiet, you choose not to make any noise and hide in the rock outcropping you have been in and wait until morning. You awake early and find that the green cloaks had been buried some time in the night, but you don't think the bandits dressed in red would have taken the time to do such a thing, however confusing it is, you didn't want to stick around and find out and risk the same fate.
