Maroo's Bazaar is a derelict Relay orbiting Mars It has been added in Update 18 as a trading place for players. As opposed to other relays, it features only the Hangar, the Main Entrance, and the Concourse. Maroo, its owner, can be found in her station at the right of the Concourse entrance.
Note: Due to a recent bug regarding Endo conversion of Brilliant Eidolon Shards, Maroo has temporarily been removed from Maroo's Bazaar to prevent further interactions in lieu being able to Hotfix the bug at the time.
The Hangar is the area players will spawn into and features multiple Liset docking bays and sporadic Liset traffic in the background. The Main Entrance connects the Hangar to the rest of the Hub with a security station. The force fields present in other relays have been disabled. Going back to your docked ship will allow you leave from there through the interaction prompt at your Landing Craft's passenger compartment. Or you can press Esc if you are on PC to open up the menu, then select "Leave Relay" to go back to the Liset.
The Concourse is the main area of the Hub, where trading takes place. It features a giant tree grown in the shape of an Oberon sculpture, as well as numerous civilians standing around.
To initiate trading, press Q or down on the D-pad in console to enable Vendor Mode (same menu for Emotes and Gear Wheel). After selecting the items to trade, a list of them will be visible above the player's head. Interested parties can then press X to initiate a trade with you.
Players are reporting that occasionally all the available player names and the items they are offering for trade, become stuck on a fixed position in the UI. This happens more frequently when more players are in Maroo's Bazaar at the same time and is sometimes fixed by leaving the relay and rejoining it.
Fixed Octavia not playing her music when dancing in Maroo's Bazaar.
Update: Octavia's Anthem
The Relays and Maroo's Bazaar now offer dedicated music zones, where you can share your Mandachord compositions and boogie down with fellow Tenno. Simply bring Octavia to one of the areas marked with the symbol in the spoiler below, and select any of the Narta emotes listed above to start the party.
Trading in the Dojo now works similarly to trading in the Maroo's Bazaar where players can "set up shop". The trading post still shows all players in the Dojo with trades remaining for the day, but Players can now start a trade from the Trading Post or by interacting with another Player who is in trading mode.
