The Nowhere Doors

The nowhere door looks to be nothing more then an eerie door in the middle of nowhere,
to those none the wiser it could be all that is left of a once majestic castle, or
even the rickety door of a long since dead hags Hovel. The nowhere door however can be a two/or one way door
to anywhere. the caster must have been to,seen, or is able to visualize the place they are making a door way to.
the caster Decides how the Door Appears IE falls from the sky,shimmers into existence, or pops up out of the ground etc
the caster also decides how the door looks and how big it is. the caster must also set a password, the door will only function for
those with the password or those given permission to enter by the caster. the door does not appear magical to detect magic or
identify spells. the door cannot be destroyed in anyway. 

if you cast this spell at higher levels the nowhere doors can lead to and from other planes.
