Each group in Murim is broken up into two different families till Aran comes along. Now there are 3 groups.
- Main Family - A group who chose to suppress their power by the poison and coexist with normal humans.
- Branch Family - The rest of the family who never gave up power and thinks they should rule all through power.
- New Murim Alliance - is the newest group led by Eun Aran but dictated by Suksoo. They have named themselves the protectors from the robots.
