Overlord is a sequel to the Dungeon Keeper seriesSomething the creators probably couldn't have driven home harder if they'd tried. The games have very similar themes (albeit different genres) and even many of the surface elements are similar, such as the tower heart and the visuals of the health meters. Obviously, then, it makes sense to connect the stories. Conveniently, the long-since-vanished Dungeon Keeper III was set to see the eponymous Keeper emerge into the overworld. Apparently the Keeper succeeded, becoming an Overlord into the bargain, with a tower instead of a dungeon for a home. Such a pity he would be destroyed by those ever-invading heroes, but hey, it gave Overlord a functional Back Story.
The Minions are distant relatives of Pikmin.In many ways, The Minions are similar to Pikmin. (e.g. attacking enemies, carrying objects, obeying commands, most of them have an immunity to a particular hazard). They even come in different colors.
Overlord is a prequel to the Dungeon Keeper seriesIn Overlord: Raising Hell, the Overlord is trapped in the Abyss. Over time, he becomes less of a Guy In Armored Suit (which isn't practical for The Abyss) and more of an Eldritch Abomination, a form that simply works better. Unable to return to the Real World in any practical matter, the Overlord settles for an intermediary: the underground dungeons of Dungeon Keeper. He becomes the Dungeon Keeper, and the Dungeon Heart is what the Overlord magically-evolved into. It makes perfect sense within the mechanics of Dungeon Keeper: Where do all your minions in Dungeon Keeper come from? Portals, Bottomless Pits that actually have a bottom, and that bottom is the Overlordian Abyss. Other Keepers? Bad Guys (and former Overlords) who have done the same thing you have. Horned Demons in DK 1 being unruly and difficult? The Overlord-Turned-Dungeon-keeper killed all but one, and brainwashed it into believing it was the Big Bad instead of The Dragon it really was. Where did the O-T-D-K get that idea from? Gnarl.
The Explosion of the Tower Heart caused Warhammer40k Warp to seep into the world and infect itWe have a human Empire led by a Golden Emperor that's dedicated to the eradication of all other creatures because they're 'tainted' with magic: The Imperium. We have a race of decadent/ineffectual scimitar swinging elves who are a dying breed and can be corrupted into sin and darkness: Eldar. The area around the first Dark Tower is saturated by a magical residue that corrupts and warps anyone who touches it into mindless savage mutated beasts: The Warp. Giant spiders/salamanders monsters that only want to devour until their hive queen/king is dead: Tyranids. And all of this is opposed by a force of pure evil that either kills and slaughters everything and everyone in its path (Khorne) or a schemer and plotter who enslaves people so that they may work towards his dark goals (Tzeentch). And of course, you have the minions. Scaly, toothy, scabby, bad manners and always ALWAYS ready to start a WAAAAGH!! What more proof do you need?!
In a DLC/Expansion Pack for Overlord II, the Overlord from the original game (the one you play as, not the Wizard) will come back. With a vengeance.Most evidence suggests that the canon ending for the first game was the 0% corruption one, or at least a low corruption one, making the old Overlord significantly less evil than his descendant, even if you go the Domination route all the way. So when he gets out of the Abyss with his armies, it'll be as a Noble Demon and/or Dark Messiah opposing your reign, leaving you to face him, with the combined power of the Abyss and the remnants of the forces of Light (since the elves owe him for, y'know, preventing their genocide) at his disposal. Luke, I Am Your Father moment/parody optional.
Gnarl is the real ruler of the Overlord's domainEvery time the Overlord dies or is otherwise indisposed, Gnarl leads the Minions, but because the Tower Objects won't respond to him, he can't fill the power vacuum and rule the Dark Tower. For that reason he's forced to keep recruiting new Overlords, but uses each one as his pawn. Isn't it strange that Gnarl spends all his time comfortable in the Tower, while the Overlord is the one putting his life on the line and doing all the grunt work. Gnarl merely maintains an illusion of subservience while he rules behind the Overlord's back.And if the ending of Overlord II is any indication, Gnarl may in the next sequel or expansion pack have found a way to make himself the Overlord with all the power the position entails
Lord Gromgard is the Old OverlordStarting a genocidal war between the elves and dwarves that would culminate with the near-extinction of one side is quite the Moral Event Horizon, even if it was Gnarl's idea. What if Lord Gromgard liked the notion of playing his enemies against each other, and grew to embrace it as an older, mightier Overlord. Manipulating his enemies to kill each other for him is certainly the Modus Operandi of the Old Overlord (Wizard) of the first game. Nevermind that the prequel is supposed to take place centuries before the first game - with his skill at Grand Theft Me, Gromgard could easily have possessed a whole string of Overlords leading all the way to the present.
The hero who would become the new Overlord in the original game was a bard.The heroes who survived the battle and became corrupted had to number seven for the deadly sins theme,but this also gave us a quite large and well balanced party with all the roles filled, assuming the paladin could provide the necessary amount of healing, but there's always room for the traditional bard. Sure the nameless former hero could have had the same class as one of his mates, but I just find it funny that, in the words of another bard, "the guy who goes into a dungeon and sings" ends up ruler of all the land. And if you don't fancy bards, introduce another obscure,"should be big time in my opinion" class in its place like a warlock or factotum.
Overlords serve as a "queen" to minions.They can't process life force naturally, due to their domain in the Netherworld. They need to run it through Overlord first. In exchange for the Overlord providing this processing effect, minions offer unconditional loyalty. Think bees with a more hardcore queen. The Overlord "spawns" new minions by converting standard life force into minion life force. Thus, the reason why minions seek new Overlords and guide them to the "evil" path is that they need new "Queen/King" to collect this life force to spawn new minions. Gnarl only serves as temporal "hive mind", since he can think, but can't process life force. Alternatively, Gnarl is some former Overlord who eventually turned into minion himself after years of collecting and processing life force. Also, now you think of Overlord and Overlad as crossdressers.
Summoner wraiths in raising hell were old overlords.
The classes for the eight heroes are:Kahn was the warrior, Jewel was the thief, Sir William was the paladin, Goldo was the ranger, Oberon was the priest, the Wizard was the sorcerer, Melvin was the bard, and the Overlord was the wizard's apprentice.
Overlord III will feature a stage where you have to defend your tower from a siegeThe one thing missing in the games was having to defend the tower, which was previously located in either Mordor or Another Dimension. In the third game, either your subjects will rebel against you and lay siege to your tower requiring you to send minions to siege engines like the catapults in Overlord II, or demons/monsters will teleport into chambers of your tower, and you have to slay them as they come out while Gnarl or your mistress acts as Mission Control telling you which room they are in.
Kelda is descended from werewolf, or even is one herself.She has a nigh unnatural knack with (and an obvious fascination) with wolves, and belonging to a race (or even a family that belongs to) who was presumably as badly persecuted by the Glorious Empire as any other magical one might explain her sympathy for the Overlad. Not that there's any implication in the game that werewolves actually exist, but hey, Fantasy Kitchen Sink.
The eight hero was never that heroic.Why else would his companions abandon him and leave him for dead? Their later corruption was due to their personal fatal flaws, but it doesn't seem to be in the nature of any of them to betray a friend. Perhaps he was the Token Evil Teammate, and they decided he was too much of a liability when they were getting so close to reaching their goal, so they decided not to revive him.
