Marie's delve into the use and application of the Heavenly Eye was controlled, stringently so. She was not allowed to use it without her Master present, nor was she allowed to observe the visions corresponding to Constants in the grand tapestry of Fate. On that note, how can one differentiate between the Transients and Constants when performing Divinations?
One of Marie's subconscious fears was unwittingly gazing into a Constant and accidentally setting into motion a chain of events that led to a deviation, which would inevitably come back to bite her. However, thankfully, the Heavenly Eye made it extremely easy to identify Constants. As she gazed into the emitted waves of fate when divining the answer to a question, the wave would decompose and turn into a net of silver strings extending in all directions, with thicknesses determining their relevance to her question. Amongst these silver strings, she would often find ones that were a pure and lustrous gold shade.
