Nexus

The Nexus is the central structure inside each team's base and the ultimate objective of a match. Destroying the enemy Nexus immediately ends the game in your favour, no matter the score, while losing your own is a defeat.

It sits behind two final Nexus turrets and can only be attacked once at least one lane's Inhibitor has been destroyed. Because everything in League of Legends ultimately serves the goal of cracking the Nexus, taking objectives, winning fights, and pushing minions are all means to reach this final structure.
