Pathfinders

There are pathfinders for each element. Pathfinders are magical items that if all found, can be used to get to the king or queen of dragons, and will help get through each challenge, not much is known about how it works, but if you found, say a fire elemental pathfinder, it'll lead you to the Fire Lord. Pathfinders will light up when held by a dragon who has the heart of that element. For example, if you picked up a water elemental pathfinder, and it lights up blue, you're connection to that element is very strong. If the pathfinder glows and circles around you, you'll be the next water lord. If all the pathfinders are met, and glow and circle around one dragon, it means they are going to be the next king or queen. The pathfinders can also be manipulated by the gemstone of confusion, and elemental magic combined, meaning a dragon can then suck all the power of the pathfinders and become a god. When you've found the dragon lord of the respective element, the pathfinder disappears to another hidden temple.
