It may come as a surprise to you that you're able to recruit every single Stormcloak soldier in Skyrim for your own personal army. What's more, you can entice Imperials into joining the cause as well - the Civil War is largely irrelevant when you're at the Dovah✨kiin's beck and 🎀call.
There's just one catch: In order to convince these soldiers that it's worth their while to join your army, you've got to kill them first. They're all going to go on about arrows in their knees and sweetrolls being stolen until they draw 𒐪their last breath - but once that happens, anybody who is even remotely adept in the arts of necromancy can resurrect them, still suited and booted for battle.
You c🍷an check out the phenomenon in action in the Reddit post embedded below. It starts off quaint enough - just a guy walking through Skyrim in Archmage robes while a cutesy little rabbit hops by.
But sure enough, the rabbit senses something. It can feel the army of the dead approachin🅰g, and scurries off into the shrubbery. The Dragonborn's follower emerges from the background, and behind her the encroaching horde of the undead progresses in single file, still remembering their military tutelage even in death.
These wraith-like corpses don't stick around for long, though. The Dragonborn's spell is sufficiently poten꧅t to keep them upright for about five minutes, but they soon expire, resuming the rest the Dovahkiin 🍒so rudely interrupted.
Saying that, there is one particularly powerful spell called "Dead Thrall" that🌸 allows you to permanently disturb their deathly slumber and ensure they become devoted to you and you alone for eternity. The joys of necromancy.
It suits this character in particular, though. Further down the Reddit thread, the poster left a comment saying that they're going for the "shady evil 🍌Archmage" aesthetic. Savos Aren is probably turning in his grave - at least until he gets resurrected to lead an even bigger Army of the Dead than Ara🍌gorn's, that is.
