Integrate an entity?

Has anyone ever been asked to integrate an entities “string of energy” before?

Entity claiming to be a certain demon asked me this.

Need to know if its a trickster or if this is a legit stage in development.

Have you tried Divination of some kind to find what the nature of this entity is, and if it’s intention is good.?
You can find the name of the Demon it claims to be, get it’s sigil and draw the energy of the Demon into yourself, or whatever object you desire to connect it to.
