Challep was the male governor of Agamar in 33 BBY. During this year, he sought to bolster Agamar's planetary defences, in particular the starfighter contingencies. He purchased technology of various groups including at least 100 Droid starfighters from Xi Char but also wanted the technology of Naboo's N-1 starfighters and N-X Police Cruisers. After, at least, three attempts to purchase the fighters that were all denied by Queen Amidala's Advisory Council, he sought to steal them instead.
