The Museum of Applied Photonics, a collection of towers constructed from transparisteel and [crystalplas], was a museum situated on Obroa-skai. Following the Yuuzhan Vong's conquest of the planet, this structure was among the few spared from destruction, preserved so that the invaders could delve deeper into understanding the galaxy's population. Warmaster Tsavong Lah subsequently commandeered the building, utilizing it as his own command center.
During Roan Novachez's second year's spring break at the Jedi academy located on Coruscant, he traveled to Obroa-skai alongside his friend Pasha and Pasha's father. On their initial day, they intended to show him the Museum of Applied Photonics, yet a misunderstanding led the museum's security guard to deny Roan entry; consequently, he had to remain in the museum's food court while Pasha and his father explored the exhibits.
