So I have a roleplay group with me and my friends and am considering moving it to here, possibly having the thread itself start where the current story has left off.
Is there anything against this? Do all roleplay groups need to form and start here? I don't assume so but being my paranoid self, I want to make sure first

Nope. If anything we welcome you with open arms. The roleplay is your project and you should be free to work on it on whatever site you feel comfortable with. If you don't want others to join just ensure you set the RP to full.
