This SCP idea was inspired from the abundance of wolf folk tales in Latin, Greek, and English cultures. Input would be appreciated, since my SCP's usually flop after I pop them on to the forums :P
The first SCP is a large, seemingly safe forest. This forest is slightly more filled with life than others you would usually see, and has a pure and untouched feeling. "The Forest" contains only a single dirt path that cuts directly through. This path has no vegetation whatsoever and is a visible marker within the forest (not hidden or obstructed). The catch is, if an individual ever steps off this path, the path will disappear and the surroundings of the forest will become unrecognizable. The forest seems to be unable to be damaged by fire, but conventional methods such as chopping and sawing prove effective. The Forest is nurtured by Oxidized iron, which allows it to spread at a rate much faster than that of a regular forest. The Forest often grows outward in branching patterns, attempting to intersect roads, towns and other forests.
The second SCP is a branching SCP, that can be included with the first. This SCP is a large wolf, jet black in coloration with a grey stripe down its muzzle. This wolf is of an unknown species and is twice as big as the average wolf. It has the ability to speak and reason just like a human, but is driven to kill by a powerful bloodlust. The Wolf uses the illusionary qualities of "The Forest" to hunt down anything that strays of the path. The Wolf does not only wait for people to stumble off the trail, but even goes to the extent of charging at them to cause them to run off. The Wolf takes joy in teasing it's victims with offers and bargains, which forces them in to making difficult decisions. Along with that, The Wolf may even stockpile victims to create a more bountiful food source, as well as a more thrilling hunt.
These SCP are retained by a large barrier around the perimeter of the forest along with armed agents to stop civilians from entering. A careful cutting process is implemented, where foresters cut from the outside going inward, making sure not to step with The Forest while doing so.
