Lestat tells us in QOTD that they survived and moved on w/o him:

“[The Coven was] relieved that the Vampire Lestat had died in the pages of the newspapers; that the debacle of the
concert had been forgotten. No provable fatalities, no true injuries; everybody bought off handsomely; the
band, receiving my share of everything, was touring again under its old name.”

Slightly on topic: @everlastingporcelain​ got a t-shirt for bangin’ Lestat’s mom! [X]
