Good Home opens the Sanzhani questline: a fairy named Heile asks you to find her missing brother Tonis. Finishing it starts Letters to Lunka and four more Sanzhani favours, whatever you choose.
Finish the Prologue. North of the Sandy Gorge Shrine, follow the mushroom rings east and crouch into a burrow. Heile is inside and asks you to find her brother.
Optionally search Oghasti and the Wooden Palace for clues. Follow the smoke west to a camp and ask the Coal Burner Chief about Tonis. Then follow the X-marked trees north-east to find Tonis alone by a fire.
At the burrow the Tsarina appears. Talk Tonis into leaving Heile behind and the quest ends at once. Or ask the Tsarina to release Heile, and she wants three shiny teeth as payment.
Skipping Oghasti and the Wooden Palace saves time, but you lose some later dialogue. Shiny teeth can also be sold to the Sanzhani.
Besides XP and a skill point, it unlocks Letters to Lunka plus Come Hither, Burrow Sorrows, Pearly and Precious and Tiny Dancer.
Come Hither
Come Hither is one of the Sanzhani favours that open after Good Home. You follow a sanzhana to its burrow and kill the murohn living there, and it counts toward Letters to Lunka.
Letters to Lunka
In this quest you send secret messages to Lunka while she is held in Greifburg Castle. Finish all five Sanzhani favours and the Tsarina also gives you back a whole day on the 30-day clock.
A Lone Wolf's Hunt
A Lone Wolf's Hunt is the ending you get by storming Greifberg Castle on your own, without Crake's or Lacra's help. It ends in the final fight with Brencis, so save before you go in.
A Mother's Heart
A Mother's Heart is a quest the wiki lists for Vale Sangora, built around a fight and the conversation that follows it. Guide sites have not covered it under this name yet, so details are thin.
