The Gungan Minister Rish Loo maintained a secret lab in a ancient temple on Naboo. During the Clone Wars, Separatist leader and Sith Lord, Count Dooku used this as his command center during his brief alliance with Rish Loo.
Prior to General Grievous's arrival on Naboo, Dooku went to Naboo where he made a deal with Gungan Minister Rish Loo. Dooku promised him that in exchange for the Gungan Grand Army's support, Loo would be very influential in his new order. However, Loo's plan failed when Republic Representative Jar Jar Binks foiled his plans and Grievous was captured.
