Extension on Anniversary Event? Pretty Please?

[Mkali-frostwolf]

If you mean the secrets stuff, that is indeed extended / accessible after the event is over:

@Linxy

Incognitro, the Indecipherable Felcycle Secrets

Alyx will make their way to Dornogal after the event ends and continue to offer clues to the locations of the Celebration Crates. Find and return all 11 Celebration Crates to earn the achievement Azeroth’s Greatest Detective that rewards “the Detective” title that will begin your investigation for the Incognitro, the Indecipherable Felcycle.

If you are missing the tools required for secret hunting after the event has ended, don’t worry! You can still get the secret tools, but through the Secrets of Azeroth questline introduced in Dragonflight’s Fracture in Time update.
