" It was a toy Court that obtained there."
I was confused like you when I read that sentence so I looked up the word 'obtain '.

1) obtain. The American Heritage:
...1. To be established, accepted, or customary: standards, proprieties that no longer obtain (Meg Greenfield). 2. Archaic To succeed. Middle English obteinen, from...

Only knew it as:
1. Come into possession of; "How did you obtain the visa?".

" It was a toy Court that was established there " is how I now understand it.(and that suits the context)
