Jedi Headquarters, located in New Republic City on the planet Coruscant, functioned as the operational center for Luke Skywalker's New Jedi Order. This edifice was erected atop the carefully maintained remnants of the ancient Jedi Temple that belonged to the previous Jedi Order.
The Headquarters took the form of a domed building, incorporating several rooms dedicated to training, seemingly inspired by the architectural design of the Jedi Praxeum situated on Yavin 4. The interior was adorned with a multitude of carvings and statues depicting various Jedi. The origin of these decorations, whether specifically created for this building or relocated from other places, remains uncertain. The Headquarters building hosted a special event: the wedding of Luke and Mara Jade Skywalker.
During the Yuuzhan Vong War, specifically during the invasion of Coruscant in 27 ABY, this building suffered total destruction. This devastation exposed the underlying foundations of the original Jedi Temple once again, which subsequently became the location where Irek Ismaren seemingly met his end.
