The Ranger Interns

The protagonists of the series. Four young adults that signed up for the Thistlewood Forest Rangers Internship Program, a summer school run by Wallace and Jermaine Foster to teach young people the work of being a forest ranger.

As they are based primarily in the woods, the rangers are exposed to a great number of the strange occurrences that plague Thistlewood, and the current interns have spent most of their time investigating different creatures and mysteries.

This year's interns are: In season two they are joined by
 * Leslea James
 * Joshuwa Archon
 * Cypress Grove
 * Jazzmyn Ward
 * Maryam Ginger-Mora

The Program
The program is intended to put interns to work in various forestry activities and teach them important skills, such as preventing forest fires, preserving animals and opening Roth IRAs. In the series the interns do things such as escort Bertha on her morning walk, run a carnival stall and some minor conservation work but they largely seem to investigate monsters, to Wallace's consernation.

It is suggested by Gustavo Haynes that the current interns are the first to take the program in five years, the same time frame as the appearance of the Varusa. Throughout the first season it is suggested and eventually explicitly stated that the Varusa first appeared as a result of Wallace and Jermaine were responsible for the appearance of the Varusa in the forest, possibly by disturbing its home.
