Welcome to Sector H, a hidden sanctuary for young superheroes all over the world. In the youth, superheroes are unbalanced and their powers can become unstable. Sector H works on balancing that issue. Join Mark, with the super strength. Fiona, with the power of Ice. Craig, with the power of fire. and Jasper, with the power of forcefields. These four have had a rough past together, and have fought many monsters before being spotted by Sector H. Along the way, our four heroes meet friends, foes, and foes who pretend to be friends, as Sector H suffers the threat of war with the Shadow Tribe; a tribe of ruthless shadow monsters of once heroic superheroes. Sector H will need to keep all of their wits about them as they plummet into darkness; a darkness that could be a one-way trip.
