This is purely a concept I (gates of balance101) thought of.

I think that all the "triangles" (such as the burmuda triangle) are gates to other realms, worlds, ect. What do we know about gates? Well most are locked, which means they need a key, But who holds the key? well usually the owner of the house that the gate is protecting has the key to unlock it. Realms do not have owners, so there must be a gate keeper, someone who can hold the key, that somemone would not be the triangle because the triangle is the gate. The gate keeper would probably not be agressive, because they keep the balance between the worlds.

In order to keep the balance though, they would probably have to have powers, so they would be able to fend off unwanted guests without harming them. There are a total of 12 gates spread out evenly across planet earth. With 12 gates, comes 12 gate keepers and 12 keys. The gate keepers, would probably not be immortal, because the humans would get suspicious of them. I think that the gate keepers would be able to reincarnate themselves so they still have their previous memories.

The keys would not be just normal keys. If the gate keepers reincarnate, so do their keys. I would think that each tim key reincarnation happened, the keys would come back in different forms each time, Ex: human, plant, inanimate object, animal.

The whole idea is to keep balance between 12 different worlds and realms.
