Aurora's Unlimited Blade Works

Up to ten swords that are not being worn or carried by another creature become bound to you and are dismissed, shunted into an extradimensional space.

Until the spell ends you can use an action to summon one sword to your hand for each hand you have free. These swords can be dismissed again as a bonus action. An antimagic field suppresses the ability to summon or dismiss any swords that you have bound to you. If this effect is dispelled, all swords still in the extradimensional space appear on the ground at your feet.

If you use an action to cast Animate Objects while you have nonmagical swords in your extradimensional space, you can summon up to ten of these swords as part of that action and immediately choose them as targets of the spell.
