A few notes on the animated sequence near the beginning:
It has the first appearance of an Aquan since TAS: “The Ambergris Element”. She is notably not underwater. (Or the Andorian next to her is notably underwater.)
It also features an Edosian, though that’s becoming less and less notable.
The Vulcan on the harp strongly resembles Sarek as he appears in TAS: “Yesteryear” down to the jagged eyebrows.
The woman on the couch holding the drink is dressed like Andrea from TOS: “What Are Little Girls Made Of?”
I don’t think it was ever “canon,” though maybe in the early eighties the novels were viewed as canon by some before TNG? I was too young at that point to really be confident. Mainly mentioning it in case you meant something closer to “incompatible with canon.”
Curious what “events” you’re referring to in any case. Not familiar enough with the novel to say for sure.
