Echoes of the Serpent (слэш)

In a parallel wizarding world where Leo Potter is believed to be the boy-who-lived, desperate to survive the war, he attempts to summon Godric Gryffindor to defeat the resurrected Voldemort. Only for the ritual to tear open a rift and pull through Harry Potter, the battle-scarred survivor of another reality who is the reincarnation of Salazar Slytherin. Harry finds himself mistaken for the legendary founder himself. Now he must conceal his true identity, uncover the fate of this world’s missing Harry Potter, navigate the dangerous attention of Voldemort, and resist being drawn into a brewing war that echoes the one he had just barely escaped.
