It would continue the plan to have the prince-king visit the ponies' land and then force the matter, with the prince-king having no idea or way to prepare himself for the war that was to come for harbouring those accursed Elements in his lands, knowingly or unknowingly. It would force the issue with the threat of war, and it would make this land's king and captains destroy the world over if it would bring the Elements to heel even if they were no true threat with the prisoner being contained under enough spells that Tartarus himself would have deemed fit only for those of the greatest of crimes, the crimes that tainted the soul beyond measurement, a shade before those in the First Pit.
