Welcome to the Demigod Alliance! We are an Alliance of Greek and Roman Demigods. If you are interested in being part of our Camp Jupiter based family, we would be glad for you to join us. -- Est. 2010 -- Whether you love the Percy Jackson series by Rick Riordan, enjoy mythology, or just want to have some fun, this is the place to be! For role playing, there is a separate group, entitled Demigod Alliance Roleplayers. Post on the wall who you would like your godly parent to be, so we can put you in a cabin!
