Are these three sentences worded in the correct way?

FYI- Quenthel is the Matron Mother of House Baenre. Meanwhile, Mez'Barris Armgo, the Matron Mother of House Barrison Del'Armgo, met with Minolin to discuss the plot to destroy Quenthel that had been created by her, the Fey-Branche priestess, and Gromph. Mez'Barris wanted to immediately implement their plan, which included utilizing the balor Errtu and his prisoner, the drow psionicist K'yorl Odran, the Matron Mother of House Oblodra, but Minolin revealed that she and Gromph would no longer move against Quenthel, since the Matron Mother of House Baenre was personally favored by Lolth herself.
