The Bosk stations are pretty much entirely underground as far as I have been able to find, which makes sense, given their ties to The Wood.
tried on piano at Servant’s Hall
Skill: Sky Stories (commited to birdsong) that still has “Attuned to Trist” with 2 trist
Honestly, it’s kind of specified in the “Attuned: XXX” flavor text:
Attuned: Trist
This skill is attuned to my Trist. [When you committed this Skill to the Tree, you gained Trist. Find somewhere with a matching Evolve aspect, and you can use the Skill – once only – to combine two Trist cards into a stronger card.]
It needs the stuff to have the “Evolve” aspect. So if you actually succeeded at evolving stuff on that piano, then we are missing something important 😡
For that matter, I don’t know what the workstation means
I thing birdsong evolves the soul cards using workstations with the instrument aspect
If it helps you, I used the piano in the servants hall to evolve via Birdsong.
Most probably all instruments can evolve via birdsong but it will require more testing
