Key Keeper

I'm the keeper of keys to all realms and it is not easy any monsters come and go trying to get the key I do not fight them I give then riddles some can answer and some can not. My riddles have a kind of magic that can detect if some one wants a realm to take over or merely just wants to enter. 
Now i'm 101 years old and people call me the boy on the branch because the six key are all attached to one great branch and I sit in the middle with no company except the ever burning lap that I have had by my side for the very start . Some creatures come and visit me but then at night they have to return to their family's so I have become used to being by my self. There is one guy though he is my best friend other than the lap his name is Cornelius he is a talking badger he brings me food and water when I need he keeps me company some nights and then some night he is with his family.

There are six realms the ocean realm where every thing is under water there is the human realm which is where the most disrespectful creatures live, there is the the realm of Narnia where king Edmond and queen Lucy rule with the high king Peter and the high queen Susan, and then there is the kingdom of darkness were all things dark and gruesome live, the 5th realm is the realm is where the land of nature and the 6th is the land where I live the most peaceful of all realms.

And now that I have told you I have to go because another monster is approaching so good bye for now.
