Nowhere is the danger of the Shoals' tetryon fields greater than in the Shadows, an area overlapping five sectors. Here, the interference is so severe that ships entering the Shadows are limited to short-range sensors, leaving them effectively blind. Unsurprisingly, raiders, pirates, and other nefarious types have used the Shadows over the centuries to hide amid the sensor echoes and attack the freighters and other ships, especially those that must pass through to get from Havley's Hope to the dilithium and benamite-rich ice world Karakka and back again. This section of the Mother Road that passes through the Shadows has since been dubbed Widowmaker Trail by local starship crews.
In addition to the less scrupulous who live in the Shadows, the area is also home to the native Ohanze population, who've always had a somewhat tense relationship with the colonists encroaching on their territory. Although a formal treaty is in place supposedly keeping the peace, the pirates and other criminals in the region hardly respect such documents when choosing their prey, and resentment is growing among the Ohanze, who consider apprehending such bandits a responsibility of the colonists and the Federation.
To date, approximately 3 Starfleet vessels have been lost in the area, possibly due to pirate attacks.
