Junction

Junctions are solo missions that allow players to progress through the Star Chart.

Mechanics
Junctions consists of a small, circular room, with a specter kneeling in the center. Each Junction is accompanied by a series of specific tasks. Completing these tasks is required to challenge a Junction's specter for control of the connected Solar Rail, which unlocks the next celestial body.

In addition to star chart progression, completing a Junction grants 1,000 Mastery and several miscellaneous rewards (typically weapon blueprints and/or quests). Junction rewards can only be claimed once.

Trivia

 * Each specter is based on the Warframe whose components drop from the next location's boss, with the exception of Volt on Mercury.
 * Players retained any star chart progress made prior to . However, Junctions themselves still needed to be completed to gain their rewards. Furthermore, Junction tasks only counted progress made after the update, with the exception of completed quests.
 * Junctions were inspired by Hyper Light Drifter.

Bugs

 * The large window in the Junctions is not solid, allowing players to knock the Specter out into space with the appropriate abilities and weapons.
