A stasis box is an element of technology crafted during the Age of Legends. Though little information of these artifacts has survived the Third Age, it is known that items held inside a sealed stasis box will never age, regardless how long the box remains closed. Indeed, from the perception of an object, or creature, placed into a stasis box, as soon as the lid of the device closes it will re-open at some point in the future. This bizarre time-defying effect is directly experienced by the gholam which pursues Matrim Cauthon. It is believed that the creature was either placed or tricked into a stasis box during the height of the War of Power, and released in 999 NE. Moreover, it is probable that the container found at the Eye of the World containing the Horn of Valere and the Dragon Banner was a stasis box put into place by Solinda Sedai and a group of fellow Aes Sedai after the destruction of Paaran Disen in the hopes that its contents would be recovered in the far future by the Dragon Reborn.
Sometime prior to 998 NE, Ishamael located a stasis box that contained dozens of zomara which later serve wine to Darkfriends at the darkfriend social. In 999 NE Graendal found a stasis box that contained Streith and Sammael also found one around the same time which contained “lots of goodies, and something else,” a possible reference to the gholam.
