The nickname 'The Robot Queen' was given to Queen Melkyre by her citizens when the wars first began.
Perhaps it was because of her percision in all things, whether it be in battle or in court. Perhaps it was her excellence. Or perhaps it was due to the uncaring attitude that her people saw in her, or the distance that she put in between herself and her people.
In any case, Melkyre learned to embrace the name, and most of her people embrassed her.
