Y/n is new to the camp and due to her dual heritage the only cabin she can stay in is the Hades Cabin. However, Percy who is also y/n’s soulmate and Chiron are VERY against her staying there since Nico stays there and it is the only place where Nico can be to rememberhis sister as it is where all her stuff atill is (8 years ago). Nico dosent want her to stay there either. Percy chooses not to tell Y/n that they are soulmates instead chooses to keep it a secret.
