A character (called "Rogue") is a high level rogue. Rogue has taken the rogue talent "Minor Magic" and "Major Magic." The choice for major magic is silent image.
If Rogue is engaged in melee combat, and creates a silent image of a fighter with a sword drawn in the square opposite, and the target believes the illusion, is Rogue now flanking the target?
In other words, if the target believes in an illusion, can that illusion be used to create a flanking bonus if the positioning is correct?
