Witchiepoo, based on what Cain said, I would say don't listen to that.
Here's what I know, copy and pasted from the given lessons.
The word 'Lycan' is short for lycanthrope/lycanthropy. Lycanthropy is the study or condition of shapeshifting into a wolf. A lycanthrope, or a person with lycanthropy, is a person who can shape shift into the full form of a Wolf while on the Astral Plane as well as become more Wolf-like on the Material Plane(mentally). Lycans may inherit their animal kinship from relatives and may feel the need to feed on raw/rare meat. A lycan can be born with vampirism and, in that case, is called a werepry.
Lycans tend to have certain physical traits such as sharper teeth then is normal for a non-lycan, faster growing or thicker hair, and faster growing or stronger nails. Fast healing is said to be a lycan trait as well. Senses being slightly increased, such as smell and hearing, are also traits of lycanism. Lycans also tend to have a knack for identifying other lycans.
Personality traits would include a wolf-like perspective on things, the longing for a social group similar to a pack, loyalty to friends, a dominant lycan would have the urge to lead whereas a submissive lycan would follow, and an unforgiving dislike for traitors."
I wrote this lesson, not all of which is posted here, back when I used the term "lycan" more frequently, as should be obvious. Now I tend to call them werewolves more often simply because that seems to be the most commonly given term.
To my knowledge, an official documentary on werewolves does not exist. Everything I can share is based on my experience with real werewolves. It is possible I was fooled or otherwise failed to make an accurate observation, so while I myself have allot of confidence in what I have found, don't consider 100% guaranteed to be true.
To disclaim a few myths: Werewolves do not shapeshift on the material plane. If you are a "spiritual werewolf" you are a werewolf. Simple as that. Werewolves are not allergic to silver, do not have an ongoing and unexplainable war with vampires(actually vamps and wolves get along quite well, from what I've seen), and do not have any supernatural enhancements such as super strength or speed.
They do not require blood or raw meat, however a desire for it exists in some. More specifically, werewolves do seem to have an urge to hunt at least on occasion, however this can be satisfied in ways other then hunting. Sports, fast paced video/computer games, or a workout routine may satisfy that urge for some.
Howling at the moon, while commonly and mistakenly associated with wolves, is not forced upon nor required for werewolves, although many of those I have met do find it fun. Wolves have never howled at the moon, they howl as a form of communication. Werewolves do not have the need to howl at all because they speak English.
And finally, perhaps most importantly, werewolves are entirely human. This is an indisputable and proven fact. You can dissect a werewolf, run a DNA test, do whatever you want, and every single time the results will be the same- he/she is human.
