Ter'angreal are tools, created during theAge of Legends, that perform a specific function. Some of them had to be used with the Power, and could only be used by Aes Sedai. Others could just be touched, or used by anyone.
After the Breaking, a few ter'angreal remain but for many, no one knows what the original purposes for them were. Research in this area are limited due to dangers that come with ter'angreal. A few researchers have been killed or burned out while studying, or working with them.
There are a few that we know about and have studied. These include:
