Read a bit more.

I flip to the next page where it describes each chest in detail, "The Chest of Fire grants you the power of Fire and Growth magic along with the sacred Flame Spear, The Chest of Water grants you the ability of Water and Ice magic along with the sacred Water Battleaxe, The Chest of Earth grants you the power of Earth and Metal magic along with the Sacred Earth Warhammer, The Chest of Wind grants magic over Wind and Lightning along with the Sacred Lightning Bow."

I close the book and look back at the chests and slowly approach the one I had chosen. I place my hand on the lid and like the mirrors the others disappeared into nothingness. With a shrug I place both my hands on the lid and slowly push it open.
