Is this small passage correctly worded?

FYI- Corvus is the kenku and Shahrokh is the djinn skylord. Meanwhile, Corvus was confronted by Shahrokh, who wanted to know the location of a magical book in the kenku’s possession that was needed to complete the powerful ritual that could free Calim. Corvus explained to Shahrokh that when the skylord had imprisoned him and destroyed his magical items, the extraplanar space that the book was stored in was destroyed. In order to learn this information from Corvus, Shahrokh had been forced to first make a deal with the kenku, who made the skylord command all of the djinns to leave Calimport for a day, preventing the powerful beings from stopping the palace from falling.
