The Museum of Applied Photonics was a museum on Obroa-skai, consisting of several transparisteel and crystalplas towers, and focusing on holographic technology.[source?] When the Yuuzhan Vong conquered the planet, the building was one of a thousand left intact by the invaders, so they could further study the galaxy's inhabitants. The building itself was taken by Warmaster Tsavong Lah as his personal base of operations.
During the spring break of Roan Novachez's second year at the Jedi academy on Coruscant, he visited Obroa-skai with his friend Pasha and Pasha's dad. On the first day of the trip, they took him to visit the Museum of Applied Photonics, but due to some mix-up, the museum's security guard would not allow Roan inside and he was forced to wait in the museum's food court while Pasha and his dad visited the museum.
