Grand Moff V. Tarkin is the current commander of all Imperial ground forces, including the Army, Stormtrooper Corps, Army Special Missions Troopers, and other classified projects. He is known for being a brilliant tactician posessed of tactical genius, and has made numerous speeches. Tarkin was the subject of a demonstrations on Eriadu.
Vladimir Tarkin VI was born to the family Tarkin of Eriadu in 168 ABY during the Eriadu civil war (well, one of many of them) and in his childhood spent most of his time around the garrison forces, he learned quickly in the ways of warfare and became one of the youngest martial commanders of Eriadu ever (at age 17) before eventually being appointed Governor Militant for his tireless service in the eradication of separatist alien forces.
After a meteoric rise in the ranks of the Empire's military upon his getting bored of Eriadu, once there were no more aliens left to kill, then Captain Tarkin assumed command of the Imperial StormTrooper Corps. Many enemies of the Empire met their doom at the tip of a blade or from a blaster barrage during this time, also much collateral damage, and some friendly fire. Due to internal strife in the Empire that was not befitting his sole focus on the art of warfare in the defence of the galaxy from all aggressors, especially his #1 perceived threat: extragalactic alien invaders, Tarkin left the Empire, resigning his commission, boarding his personal Imperial class ISD, Eternal Crusade, (and effectively stealing it from the Imperial fleet, though it was so old nobody minded much) he embarked on a journey into the unknown regions... for unknown purposes.
During his retirement phase, he travelled the unknown regions, doing who knows what out there with his personal Star Destroyer and a company of troops loyal to him personally whom had served along side him since Eriadu and came along to the Empire with him, as well as some others. What he found there and what he did there would be unknown to the galaxy for many years until recently...
