I'll copy and paste this information from another website. It's one I created.
"The word 'Lycan' is short for Lycanthrope/Lycanthropy. Lycanthropy is the study or condition of shape-shifting 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. 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. A Lycan's sense of smell also allows them to sense whether or not a fellow Lycan is near.
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.
Certain fantasy traits, traits that aren't among real Lycans nor related to Lycanthropy, include being allergic to silver, fearing fire, being allergic to certain plants, and having to transform physically into a wolf or having to howl at a full moon. These traits come from Hollywood and various authors.
There are several breeds of Lycan and their breed is the breed of wolf their spirit associates with. A Lycan who is a Gray Wolf on the Astral would be a Gray Lycan, but people don't usually point out the breed of Lycan as often as they do the breed of wolf. Most commonly for Lycans there are the Gray Lycan, the Arctic Lycan, and the European Lycan.
Just because a Lycan happens to be born in Europe doesn't make him a European Lycan, he would be a European Lycan because his spirit is a European Wolf. The Arctic Lycan would be a White Wolf. The specifics on a Lycan's Personality Traits that come from them being a Lycan would depend on the breed of Lycan they are.
Arctic Lycan may be a bit more on the quiet side and frown more upon weak-links, European Lycans may be more aggressive and more short tempered, and Gray Lycans are probably the friendliest of the bunch. In spite of being, or perhaps because of being, the friendliest of the bunch, the Gray Lycans can also be the most deadly. Being Friendlier, they travel in larger Packs and as all Packs attack as one angering a single member means angering a larger group of fearsome fighters."
That's all the information I stashed on a website I made. I'm not providing the link because it's a private site for close friends and family of mine.
