In the Inheritance Cycle series by Christopher Paolini, Brisingr is the third book, and it introduces a new portal to the world of Alagaësia. The portal is a magical gateway that connects the world of humans to the world of magic, where dragons and other mythical creatures exist.

The portal is discovered by Eragon, the main protagonist, and his dragon Saphira, as they search for a way to defeat the evil Empire and its leader, King Galbatorix. The portal is hidden in a ancient ruin, and it requires a specific combination of magic and knowledge to open it.
