vampires holy objects typically do not affect them, they can be killed by decapitation, they heal very quickly and have superhuman reflexes/senses. with age a vampire can go out in the sun, though it's typically very uncomfortable for them to do so, so most tend to keep late night hours. they do drink blood - animal or human (though human is preferred) - to survive. mostly they keep their numbers up by siring new vampires, but there are some sub-sets (not turned vampires) of vampires out there that are actually capable of breeding and having children of their own.
werecreatures are warm blooded beasts, for all intents and purposes, and they are bound by the full moon. bitten or born werecreatures shift during the three days of the full moon, older werecreatures might be able to fight off the change but it's rare and painful for them to try. they are highly allergic to silver, and if too much is introduced into their system by any means they can die from exposure. the normal lifespan for werecreatures is up to five hundred years, but the aging process slows down for them once they hit the age of 30. a bitten werecreature stops really aging once they are bitten though. being bitten isn't something that most humans can survive, it's very painful and a person becomes very ill after receiving the bite. female werecreatures, born and bitten, can become pregnant though they will remain in their human form during the duration of their pregnancy.
humans typically just your average joe trying to get by in this new world, some hunt the supernatural while others just co-exist beside them. though there are some out there who hold special powers; telepathy, superhuman powers (mutants if you will), psychics, mediums, empaths, witches (black and white magic users) and telekinetics. there could be others out there, but overall these are typical.
angels god's warriors who were sent down to earth in order to fight the evil of the land, and bring peace. they are affected by unholy objects, unholy ground, and the longer the exposure to these objects the longer it takes them to recover. typically taking them to holy ground, a church, will heal them fairly quickly. they do have free will, to an extent, and their grace is basically their soul - though it is not theirs to trade or give away freely. they are free to love whomever they'd like, and they can have children with humans, other angels and in very, very rare cases demons. angels can fall by partaking it too much sin. please note that god or jesus are not playable character here at this game, and that one month on earth equals ten years in heaven.
demons lucifer's legions sent up to destroy mankind, and drag their souls to the fiery pit. they sow discord, distrust, and cause overall chaos when they can manage it. they are affected by holy objects, holy ground and the longer the exposure the longer it takes for them to recover. typically taking them to unholy ground, or back to hell, will heal them quickly. they have free will as well, since they have lost their grace after their fall - or they had none to begin with - and thus they are free to indulge in whatever they like. they can have children with most other species, though if they have a child with a human, that child is called a hellion and does bear a glimmer of a soul. it should be noted that one month on earth equals ten years in hell.
others your imagination really is the limit. we are accepting of all different sorts of supernatural species from all sources of folklore. gods/goddesses, shapeshifters, dragons, ghouls, whatever the case may be. i do ask that if you're playing a species that isn't listed here, that you link us to source material somewhere in the biography, or when you drop off the link to your biography.
