Druid of Yggdrasill

The Yggdrasill is known as the World Tree and connects the realms. This strange tree grows as the universe is expanding, gaining more and more power. Yggdrasill dose not want to rule the world with its power but wants to bring it together. The tree has most of the realms in its roots but there are five realms in its canopy and trunk. These realms are Ásgard, Olympus, Haven, and all other godly planes are in the canopy when earth (AKA Midgard, the mortal world, material plane etc.). There is a piece of the tree in every realm, and a tree allows you to find and access it. People that are the tree's "champion" can access a miniscule fraction of its power. These people are called "Druids of Yggdrasill". Druids of Yggdrasill are created after the tree chooses them and allows them to access its land to travel the realms and see from its children (plants). Some people call this phenomenon "Forestall Enlightenment". The Druids of Yggdrasill are rare and are extremally powerful and wise. This is obviously never proven but if it was, the world would be in danger. This knowledge being proven would drive a new era of Druids looking for Yggdrasill and trying to force it to give them power.
