ok ok ok so when your first come in to your new world of the spiral you have to defeat some kroks but then when you get into the krokospinx you help the kroks and the balance school in run by the kroks
Some kroks are good and some are bad.When the kroks first came they took advantage of the manders and soon the kroks died out then when they came back some wanted to take advantage again and some wanted to help them.
That's one of the good things about the Wizard101 world. It doesn't have the idea that whole races can be 'good' or 'evil'. There are individuals who are oturight evil, and others (like the Marleybonians in Krokotopia) doing things that they think are good and others might call evil.
There are good kroks but the bad ones are kroks too but the bad ones are called tuts if I remember correctly in the krokosphinx you Try to bring the order of the fang back together if I remember the dialogue correctly or something along those lines.
