A few things:

In the writing of this draft, I am simplifying. All of the ideas I’ve had need to come together, now, into something fairly easy to remember and do.
Alternate options are available for most things. This is my ritual widget, but please do feel free to change it up to suit you. Take a look through my documentation. There are lots of ideas for alternate names and gestures and other stuff to get you started.
This is by no means a final draft. As of the time that I am writing this, the ritual widget has not been tested in the form which it is about to take.
The Greek needs a decent scholar of ancient Greek to check it for me. I think it’s ok, though. ::shrug::
Ritual widgets like this one are hard to understand in print. I am not going to do YouTube videos for the foreseeable future, unless I can find some people to help me with that. Seriously, if you do a YouTube video of this ritual, and link to me, I’ll love you forever. The more exposure this gets, the more eyeballs there will be to catch simple mistakes I may have missed.

To review:

This ritual references the mythology of Hermes and Hekate as it pertains to the Crossroads.
This ritual is to be used only in circumstances where an actual three-way crossroads is not available
Once this ritual has been cast, the way to all places in the Greek Cosmology should be accessible
This ritual is a good way to prepare for spell work or for any religious ceremony calling for a crossroads
