Tyche first appears in Surprise Melody Flintkote 2. At her first actual mention...she is two...and Australian by birth. Gold Coast.
When I started writing about Tyche, she had her Bengal brood chipped.
That she was chipped was supposed to be a joke.
Wasn't.
The first chipped human was 2004...in 2021 Tyche was exactly old enough to have been chipped at birth. She was.
