join my alliance, the Warriors of Poseidon
You shouldn't even have told him to join your alliance. First, because he isn't on this world. Second, because the world will close in 23 days. Third, because that's your alliance and he would have been really disappointed by the game if he had joined
Ranbeer, if you want to find an alliance, post in your World's forum, in the Alliance and Recruitment section, which can be found
here ;-)
