— Summary on

3 Slytherin Marauders is an AU Harry Potter fanfiction written by severusphoenix, found here.

Petunia Dursley, Dudley Dursley, and Harry Potter leave 4 Privet Drive and — after Petunia recovers from being shot — take shelter on a dragon reserve, thanks to Severus Snape. With help from Lucius and Draco Malfoy, Rosmerta, Tom Riddle, ex-Auror Hugo Savage and a dragon named Yvane, they start hunting Voldemort's Horcruxes.

  • Must Have Caffeine: Snape. As Harry says, "World's Best Father - After Three Cups Of Coffee".
  • Noodle Incident:
    ...[R]egistering one's [Animagus] form was really just [...] ensuring the wizard knew the magic well enough that ministry obliviators and curse breakers would not be summoned to a muggle's garden to deal with a partially transformed flamingo - one time of that was more than enough.
