When the bridges of Skyway City were built, the Trolls simply came with them.
– Paragon City Legend

Trolls. The very word conjures an image of mythic monsters from Scandinavia. No gang is more feared in the Hollows than the Trolls of Paragon City. They are the “boogie men” that parents use to frighten their children away from the temptation of drugs and life on the street. The Trolls are a focus of Paragon’s urban myths, like New York’s sewer alligators or Miami’s Bloody Mary. Some stories say the Trolls are a deformed offshoot of humans, while a few others believe the Rikti were somehow behind them, long seeding the world with mutagenic drugs. The real story is even darker.

The first Trolls appeared in Paragon sometime in the early 1980s. Early police descriptions of the Trolls were similar: homeless individuals, often with a criminal record, and always long-time drug users. Although the first Trolls had no connections to each other, as stories of their condition grew, they began establishing ties to each other.
