Portal Stones are large, cylinder shaped gray stones covered with hundreds or thousands of archaic characters. They provide entrances to possible versions of the world of TWOT. They believed to be older than the Age of Legends and Aes Sedai. In the AoL they were used by the most powerful ones to journey, – by those who could Travel, – and Aes Sedai studied them but it is believed that they never fully understood them.
Usage of a Portal Stone Edit
Each symbol corresponds to another stone in the 'network.' A strong channeller of the One Power can use them to travel to other realities or other possible timelines or simply other locations in the real world, by channeling into the appropriate symbol of the target world. The symbols on the top half of the Portal Stone stand for worlds, (other realities/timelines), while the symbols on the bottom indicate Stones on other locations in the real world of TWOT. Not every Stone connects to every world and Aes Sedai of the AoL believed that there were possible worlds no Stones at all touched.

Studying of Portal Stones paved the way for the formation of the Ways; it is believed that perhaps the Ways are even in another, otherwise empty world, found by a Portal Stone. No one is sure; Aes Sedai have long forgotten.
The book Mirrors of the Wheel is known about the worlds and it is generally thought that no copy of it survived the Breaking whole.
On the continent of Seanchan, portal stones were used to bring back creatures such as grolm and raken from other worlds to aid in the fight against Shadowspawn; these animals are now a regular part of the Seanchan army.

Usage in modern timesEdit
Lanfear, traveling as Selene, uses a portal stone to transport Rand, Loial, and Hurin to a parallel world while they are sleeping. In this new world Rand's party follows a trail where the Trollocs they are hunting in their world will be. Later, under the encouragement of Lanfear/Selene, Rand uses another of these strange columns to take them back to their world.
When Rand is trying to get to Falme, he uses a portal stone again, but accidentally moves them forward in time about four months.
