The Ancient Device, or Portals is one of the spawn points in the Aberration DLC. It is a straight forward path that leads deeper into the depths of Aberration. Although it is considered the "easiest" spawn point in Aberration, the lack of water (berries and mushrooms being the only steady supply) can present a challenge. Also the greater amount of Raptors make this area quite dangerous for survivors to actually start their journey here until the Bolas are unlocked, making the raptors easy to tame. This Portal was made by Diana and her fellow tribe mates, which according to the explorer notes took years to make. These portals play a role in the Ascension cutscene for Aberration as the gateway to Extinction.
