New Holstice was a location in the galaxy which had medical facilities associated with the Galactic Republic. The people from New Holstice hosted a monument to Jedi lost in service to the Republic.
By the third year of the Clone Wars between the Republic and the Confederacy of Independent Systems, the monument, which was a cylindrical habitat of glowing memory moths, could allegedly be seen from orbit given all the Jedi lost in battle.
