The Higher Entities (Death, Fate, Luck, Chaos, Change, Time, Magic and Life) send Gellert Grindelwald back to life and give him a task: raise Hadria Potter.
In addition to the main story, it has several side-stories.
Contains examples of:
- Adaptational Heroism / HeelFace Turn: Gellert.
- Adaptational Villainy: A very, very mild example with Hadria, who's much more of an Anti-Hero (or anti-heroine) than Harry ever was.
- Anthropomorphic Personification: The Higher Entities. They also appear in Crossing-Over, another fic by the same author.
- Back from the Dead: Gellert, Hadria and possibly Tom.
- The Beastmaster: Hadria. Her pets, as of chapter eight, include a Grim (a real one, not Sirius), a Boggart, a Lethifold, a Jarvey, and an owl, and in Psithurism she gets a Basilisk.
- Crash-Into Hello: Hadria and Severus, in Schicksalsschlag. Played with, since it doesn't lead to anything romantic (not least because Hadria is physically ten at the time), but it results in Severus having to look after Hadria until they find Gellert.
- Creepy Child: Hadria is a heroic example.
- Do Wrong, Right: Gellert's advice to Hadria.Gellert: ...if you must continue your prank war, make sure they can't pin it down to you. If you must wander anywhere close to the forbidden areas of your school, make sure you aren't seen.
- The Ghost: Tom Riddle has yet to appear, despite being listed as a main character.
- Just Desserts: Peter Pettigrew gets eaten by a Lethifold in Ingluvies.
- Meaningful Name: All over the place, ranging from the obvious ("Snag") to the not-so-obvious.
- "Geist" and "Nacht" are German for "ghost" and "night".
- "Hadria" is the feminine form of Hadrian, which may mean "dark", and sounds similar to "hydra".
- "Scáth" is Irish for "shadow".
- Only Known by Their Nickname: Hadria's real name is Harriett. Subverted with Gellert; he goes by the name "Gerwald Grinsen", but unknown to him Hadria knows who he really is.
- Parental Substitute: Gellert for Hadria.
- Shout-Out: Two of the passwords Hadria sets for her trunk are [[Literature/theLordOfTheRings Mithril and Athelas]].
- The Stoic: All of Slytherin House; when the Weasley twins prank them with giant centipedes on their table they continue eating calmly without screaming or causing a fuss. Downplayed, since they are angry and, in Hadria's words, "grossed out" at the twins' prank, but they refuse to let the rest of the school see it.
- The Trickster: Scáth.
- Troubling Unchildlike Behaviour: The majority of things Hadria does. Justified, since she's really over two hundred years old.
