Lost and dangerously low on fuel, the Lightning League searches for Gate World, a legendary gateway to any spot in the universe. Gillian adapts the scanner and the Pride lands in the center of some stonework on a beautiful planet. Unknown to them, Saw Boss is tracking them hoping to follow them into Gate World where Monster Mind vines can be spread everywhere instantly. The sun rises, shines on the stones and points the way. Monster Minds arrive and the Pride takes off, but Brock hasn't returned to the ship and Flora goes after him. The barge is caught in the gateway and Flora is left behind with Monster Minds. Jayce returns for Flora but must hurry and not be caught in the gate between realities for eternity. Jayce, Flora and Brock make it back to the Pride in the nick of time and Monster Minds are kept out of Gate World.
