The Oracle derives its architectural design from the famous Oracle of Delphi. In ancient times, travelers would venture to Delphi from all over the known world, seeking the advice or answers about their future from the Oracle there. A priestess known as the Pythia, would go into a deep trance, and utter the words of the Gods to the questioner. While her words were sometimes clear, often they were shrouded in mystery.

Three great 'maxims' or sayings were etched on columns in Delphi, which have survived to this day: "Know thyself", "Nothing in Excess", and "Go surely and Ruin is at Hand". Here at the Temple of Hecate, these maxims have been reproduced and incorporated into the domed roof, in their original ancient Greek.

Another feature of the building worthy of note is the symbol in the awning over the main door. It combines the Greek cross (a symbol of the crossroads, and by extension the Goddess Hecate), a keyway and two crossed keys. One of the traditional symbols of Hecate is the key, representing Her aspect as the Unlocker of Mysteries and the Shower of the Way. This combined symbol is the official insignia of the Temple of Hecate Online, and is repeated within the Main Temple. It is also used on the interface as a button for accessing the main Image Map (which can allow for quick navigation through the site).
