Lexico suggests _entreat_ for _intreat_ and has
> entreat²
>
> _archaic [with object and adverbial]_ Treat (someone) in a specified manner
>
>> ‘the King, I fear, hath ill entreated her’
which seems to fit admirably: "Creation was treated evilly."
(Lexico's example sentence is a quote from Christopher Marlowe's _Edward the Second,_ which shows just how archaic it is.)
