This article is from the Anne Rice FAQ, by Laura Ann lat13@columbia.edu with numerous contributions by others.
When I say cameos I mean any time that a character or plot point
from one of Anne's books makes an appearance or is referred to
in another book. Specifically:
David Talbot and Aaron Lightner are referred to in both TWH and
VampChron books.
Ramses is mentioned in TVL.
In TotBT, when Lestat meets David in Amsterdam, David is getting
the Rembrandt portrait of Deborah for Aaron that was mentioned in
TWH.
There *might* be a VampChron cameo in Taltos when Ash refers to
other supernatural creatures that have taken a liking to
the Talamasca (he could be referring to Lestat or Khayman) but
this is uncertain.
