Finally my own base, I kinda want to explore the world, But I need to know about this world first, Use my phone to where am i at. I found out that i'll in vale, That's not only kingdom i'm in, They are five kingdoms around the world, Vacuo, Vale, Atlas, Mistral and menagerie. The kingdoms were infected by so called grimm, It must be that i encounter that grimm, But this one is not the only one, They are shake and sizes like the version of animal counterpart, I keep reading all of the files, They are two species, one humans and the other faunus. Faunus? They are humans with animal trails like ears and tails, The humans "However" discrimination them like animals, The 4 kingdoms are corrupt like hell, Except menagerie, The country was run by Faunus homeland. But they is another problem, The group called theirself white fang, The leader named was sienna khan who was the second incharged, since the previous leader retired, The problem is, they are terrorist who attack the SDC. But I heard that white fang second lieutenant named adam, I saw that he attack villages, along with his loyalists to forces faunus to join his caused, I felt angry at them for not sparing others. But that didn't stop there, The white fang next step is to attack the villages.
