Fantasy setting with a big ol' war going on between a bunch of different armies, whose uniforms were seemingly colour-coded, like in Bladestorm or Planetside 2. There were a few different human factions, some of which weren't entirely at war with one another (I think?) and an army of zombies, skeletons and human soldiers led by a duo of necromancers: a man, who looked like a vampiric version of Tywin Lannister, and a creepy young woman who I believe was his daughter.
I can't remember which army I'd been with earlier in the dream, but once I encountered the other factions properly I shifted my allegiance to the necromancers, since they seemed both the most sensible and the most powerful. Also they looked cool.
I threw my lot in with them and helped the daughter (who at that point was leading the army herself) strike at an
enemy base and free her father from a tomb where he had been bound 'n' banished for... a long time. Part of the reason I turned coats to serve them was, well, vampires, and I figured he would be very greatful to those who freed him, possibly enough to grant me immortality. Also his daughter was kinda hot.
Towards the end of the dream, once battle was starting back up again between all the factions, I encountered a group of soldiers (possibly mercenaries?) I had known earlier, from a few different human armies. Despite being more-or-less on different sides, I found them having a friendly chat off to one side of the battlefield. (Hence why I don't think all the factions were entirely at war.)
They greeted me with some annoying joke (I don't think I liked these guys in the first place) and I drew my blade and attacked them. They backed off for a bit- the combat seemed to be quite unrealistic and videogame-y, so a fight could take a while without someone dying, and an attack wasn't as serious as you'd think- and asked what was going on, I explained that I fought for the necromancers.
To that they were somewhat sympathetic, they said they hadn't realised one of the zombies had gotten its hands on me. I was somewhat puzzled, and insisted that no zombies had got their dirty hands on me. After a moment I realised that the undead troops of the necromancer's army could actually turn humans (not make them undead, just force them to serve the necromancer) by touching them with a bare hand, and my ex-comrades were confused as to why anyone would actually
choose to fight for the vampire.
"They're the most sane and relatable of
all the factions vying for control!" Said I, then lunged at them.
I thought that was rather witty.
The dream ended a little while after that. Was a fun ride. Wish I could remember more of it.
