Ordis has always been a direct assistant to Warframe players on their ship, and now he’s set up an operation for you to complete, Ascension. You’ll earn various rewards for completing Ascension and Operation: Belly of the Beast, which you can redeem for rewards at his vendor.
Ordis is a REAL one for this | Warframe (spoiler)
Tracking down Ordis from his vendor can be tricky. You may miss the exact location you need to visit to find him in Warframe, and he has several items you can grab. These items make excellent rewards for players looking to build up their Arcane supply or if there’s a specific Warframe Blueprint they want to track down, such as components associated with the Jade Warframe.
You can find Ordis by visiting the Mercury, which should be located near the center of the solar system, west of Earth. Ordis operates at the Larunda Relay. However, not every player in Warframe has access to the Larunda Relay to talk to Ordis. You'll need to progress through Warframe's main missions, work on the larger story, and make sure you've unlocked the main story content of Jade Shadows.
This won't be a permanent location for Ordis. After the Jade Shadows event and the first launch, the vendor of Ordis will go to Drifter's Camp. It's a location that you can find on Earth, next to Cetus.
