This request was very simple and Elena had no reason to not help Esfe, so she immediately agreed. After that, both of them started to work together on this project.
Esfe's power of illusion was very special. It was not just imaginary but could even manifest into reality under special conditions. This secret realm fulfilled such special conditions, so inside it, Esfe was akin to a god of creation.
She used that power of hers to create a model of Elena. It looked exactly like her except for being less beautiful and mysterious than the real thing. Obviously Elena's beauty and atmosphere was not something that a imitation could copy.
But then Elena started to infuse her own aura into this model. Little bit little, some changes happened and soon the model started to actually look very similar to Elena. With the infusion of her mana, this immitation was now closer to being a part of the real one. This was exactly what Esfe wanted.
