Deep Core
From Star Wars: The Old Republic Wiki
Hidden within the densely packed mass of stars at the very heart of the galaxy, the Deep Core (also known as the Deep Galactic Core or Core Systems) was a small region that hid unusual worlds. The Deep Core was home to the galaxy's oldest stars, at its center was a black hole surrounded by antimatter and dense star clusters. Due to the gravitational pull of the vast number of stars, local space-time was severely warped, making hyperspace travel difficult at best.
In the game, there is only one planet accessible in the Deep Core, the start planet for the Jedi:
