Homebrew Werewolf Species Details

Ordinarily when one hears the word “werewolf” the mind immediately flashes to vicious beasts with who inflict infectious wounds that cause ordinary people to transform against their will upon the rise of the moon, wreaking havoc on settlements.  This is in part true, though it is not the full story.  The trait of lycanthropy belongs to an ancient tribal race, many of whom live in secret—pretending to be human.  True, or natural born werewolves are able to control their transformations, and are raised to understand and make peace with the beast inside of them.   

Heart of the Wolf
Werewolves are familial loyal people who value trust and sticking by those close to you even in the direst of circumstances.  If a member of a werewolf pack is captured and taken for execution by humans, the rest of the pack will do everything in their power to free them.  Though they are not loyal to the point of suicide, part of being loyal to their group is ensuring that actions taken are for the good of the entire pack rather than the individual.  A lone werewolf is an incredibly rare sight, and werewolves without a pack are regarded by their kind as freaks.  Werewolves are fiercely loyal to their pack and are painfully slow to trust.

Beast Within
All werewolves must content with The Beast, their inner self—the form of the wolf.  There is something deep within these people, something animalistic.  While outsiders perceive werewolves as mere beasts.  A werewolf is not evil, and wolf instincts are not necessarily violent.  Werewolves value freedom, they value preservation, and above all are devoted to family.  Wolves are ambitious, they are uncouth and often far from shy.  A werewolves violent impulses are only seen when there is a tangible threat, and while they may feel them they are capable of suppressing them.  Still, werewolves are often quicker to fight than most, their overwhelming strength and feral instincts allow them to tear through those that threaten them or their families.  And as werewolves are devoted to their friends and family, they have no such need to protect outsiders and are often fiercely territorial. 

Animal Traits
Most werewolves, unless they have actively trained to appear otherwise are somewhat wolf-like in appearance and demeanor.  Their natures are far more connected to the primal than other creatures, and though they are immersed in nature it is in a distinctly different way than an Alfarri.   Werewolves tend to have gruff personalities, but not always.  They sometimes lack manners.  They often do not like wearing much clothing, and tend to spend a lot of time in wolf form—many werewolves feel more comfortable in that form.  They often grow more hair than humans, thick beards and body hair, and long locks.  A werewolf can always be picked out by another of their kind by the wild in their eye.
