Giant Shadow Werewolves were all in possession of white fur in their werewolf form.
There was a generational reason for this. One that had been passed down from generation to generation.
For hundreds of years, it had never changed.
In fact, it was a part of their identity.
When Giant Shadow Werewolves moved, it gave one the impression that the wind had passed. This was especially true since their white fur against light had certain properties that gave one the impression that they could not be seen when moving very fast.
Hence their name. Given the incredibility of their nature,
Even when other kinds of werewolves, like the Ironback Werewolf, married into the Giant Shadow Werewolf Pack, it was always the same with the offspring.
The genes that the Giant Shadow Werewolf Pack carried were just that strong and incredible.
There had never been a deviation from this norm.
At least, not until now.
