Each Tor circuit is made of 3 Tor relays. In the example above, the connection to **tails.net** goes through the 3 relays **drk**, **kicka**, and **Quetzalcoatl**.

Tor uses only 2 different relays as your entry guards, as a way of [protecting against *end-to-end correlation* attacks](https://support.torproject.org/about/entry-guards/).

Your entry guards change every time you restart Tails.

The third relay, here **Quetzalcoatl**, is called the *exit node*.
