what’s the team named? that could be the name of it, like ‘the ______’
or ‘society of _______’ [maybe justice, freedom, equity, integrity, virtue, etc.] it could also be ‘______ society’ and instead of society you could put something like association, league, union, alliance, fellowship, brother/sisterhood, faction, sector, etc.
or septenary means a group of seven but it sounds kind of weird imo
and here are some other names just because
the seven
one of us
one for all
the fight for justice
justice for all (yo its america)
amity (but that sounds like I took it from Divergent)
one of seven
seven heroes
uhhhh... idk i hope this helps
