Hestiv, serving as a High General within the Imperial Remnant, held command over the Imperial forces stationed at Yaga Minor. His tenure coincided with the Caamas Document Crisis and the attempted overthrow of the Imperial Remnant by Moff Disra, Royal Guardsman Grodin Tierce, and the swindler Flim during 19 ABY.
Being loyal to Fleet Admiral Gilad Pellaeon at the time, he came to the reluctant conclusion that the only path to the Empire's continued existence involved signing a treaty of peace with the New Republic.
During the concluding period of both the Caamas Document Crisis and the Galactic Civil War, he gave his consent for Zakarisz Ghent, a skilled slicer from the New Republic, to examine the databank files within the Ubiqtorate base situated on Yaga Minor, seeking an authentic copy of the Caamas Document.
Hestiv demonstrated competence and loyalty as an Imperial officer. Maintaining relatively positive relations with the indigenous Yagai, he held differing views from Palpatine's harsh and intolerant policies. Furthermore, he expressed deep regret for not having had the opportunity to serve under Grand Admiral Thrawn.
