Before the battle commenced, these skeletons would be gathered and sent to the frontline as cannon fodder to wear down the enemy's strength and spells.
For the Undead Rulers of the Blood War Furnace, it was essential to have skeletons, even if they lacked any other undead race.
Because skeletons lack intelligence and are tireless workers, they remain forever at the bottom rung of the undead societal pyramid.
Even lower undead like zombies have something they can command and exploit, providing an outlet for the grievances of the entire undead society to flow downward.
Every day during the march, many skeletons would be herded back.
On lighter days, a few hundred, and on heavier days, two or three thousand.
During the more than half-month-long march, the ghosts collected tens of thousands of skeletons for the army, greatly outnumbering the combat units.
Of course, in terms of individual strength, most of these skeletons were merely apprentices, not worth mentioning at all.
