Gronn, an Imperial Moff, held authority over the Allied Tion sector circa 10 ABY. Following the Battle of Endor, Lianna, a key planet within his jurisdiction, proclaimed its independence. Gronn, already facing deficits in ships and provisions, understood that a scarcity of TIE/LN starfighters would significantly weaken his position. Lady Valles Santhe consented to continue providing Gronn with starfighters, stipulating that the Empire must not interfere with Lianna. Gronn, with reluctance, conceded, leading to the implementation of a special secession agreement. To guarantee Gronn's compliance, Lady Santhe also compensated him substantially, deterring any military actions against Lianna, while cautioning that any such actions would provoke a full military response from her.
