Some race settings of certain races are a bit confusing:
Is there a certain reason why Calabim don't start with death mana?! With their vampires it's pretty much 'THE' undead race.
They aren't undead, they are very much alive. They embody the sphere of the base, carnal, fleshly desires, which the undead don't really possess. Vampires are living men and women who practice a dark ritual allowing them to draw power from the souls of those they murder, using this to grant them eternal youth and superhuman strength. This presumably deprives their victims not only of this life but also the next. Vampirism cannot be passed on unwillingly, and there are no innocent vampires.
Vampires are not killed by sunlight, but it feels very unpleasant to them and deprives them of their normal superhuman strength. This is a curse placed on them by Lugus, the god of the Sun, since Alexis's first victim was an acolyte of his. Most assume that this is meant as revenge and eternal torment, but I believe that it is really the power of Lugus empowering their own conscious to make them feel guilty for their crimes, or supplementing their conscious with another punishment if their conscious is totally dead. It is not in the nature of Lugus to punish except so as to point out sins so that the guilty will remember them and be drawn to make amends. I am of the opinion that the curse would vanish if a vampire gave up using the rituals, but perhaps not until they cease to reap the benefits from their previous murders. For older vampires that would probably involve starving themselves to death, but at least they would find forgiveness and a place in Lugus's heaven after that.
As Lone Wolf said, many of these living vampires are experts on necromancy, since they have no scruples about desecrating corpses, a lot of corpses to spare, and lives long enough to allow them to spend centuries masteing the dark arts.
According to the manual Luchuirp are supposed to be good dwarves. Why are they using bone golems? Wouldn't it be better to give the 'evil' golems to the Khazad dwarves, since they are at least neutral?
What is so evil about making golems out of
ivory from long-dead mammoths? This isn't necromancy, and it doesn't even defile the corpse of any sentient being. (Although I suspect they would really like to make a Bone Golem from Dragon Bones if they could and Dragons in Erebus seem more intelligent that humans. They probably only use bones from an already dead dragon though, or hire some adventurers to kill and evil one. Of course, I'd be afraid that dragon bones are saturated in mana of the dragon's precept and maybe haunted by the dragon's spirit, so a Dragon-Bone-Golem might have a will of its own and would be hard for the dwarves to control.) As you'll see from the pedia, a Bone Golem can only be fashioned out of a single piece of bone, so the Luchuipr would only be able to create toy golems a few inches in height if they used human bones for this.
Further, shouldn't some religions be restricted to certain alignments? The favorite religions for Calabim seem to be order and empyrean. It's a bit odd if the best religions for a certain race are those of the opposite alignment.
The Order fits them fairly well thematically, but I do tend to think that the Calabim should be blocked from using the Empyrean. In my version, I increased pretty much all religious weightings, and gave all Calabim leaders but Decius (who of course should follow the Empyrean when he leads the Malakim) a -99 weighting towards the Empyrean (which means the AI will never use it, but a human still could). I also made "NONE" be the Calabim UU for all Empyrean UUs, and make Blinding Light deal holy damage to units with the Vampire promotion or give them the Withered (renamed Enervated, since I like the old Entropy III spell's name better) promotion (depending on which one of my versions I'm talking about).
Actually, what's the point of alignments if they don't serve any purpose and can be changed as easily as underwear? Wouldn't it be better to remove them entirely since the game mechanics doesn't seem to care about them?
Some game mechanics care about them. I'd prefer the system be expanded, using Broader Alignments and adding a lot of events that can change or have different options based on your alignment.
