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.
Despite these setback, Lord Sidious, ordered Dooku to make prisoner exchange by using Jedi Knight Anakin Skywalker to retrieve Grievous. Thus Dooku ordered Loo to lead Skywalker to his lab. Loo was able to lead Skywalker into his lab. However, Dooku, seeing Loo as fool, killed for his failure. Skywalker fought Dooku and his MagnaGuards until he was subdued by him. Dooku then contacted Senator Amidala to arrange a prisoner exchange for General Grievous.
