The equality secret society in short TESS. Started with a girl who noticed how unequally treated were the students in hogwarts simply because they were in different house or different gender or different age or different blood status. She began to act first just her hexing the bullies, next few friends joined, shortly a large group formed. They organized many actions in secret. No one was entirely sure who started it, professors either supported their actions or they didn’t know about it as almost never anyone got in real trouble because of it.
