Incognitro, the Indecipherable Felcycle

This demonic machine was designed by Chief Engineer Ulzik as an experiment in cross-dimensional traversal. Despite many deaths during testing, Ulzik remained confident that this vehicle would reveal secrets of the universe previously unknowable.

Notes:

This fel-themed bike is the reward for a special 'secrets' quest chain that follows on from the WoW 20th Anniversary event (and requires completion of some Anniversary achievements). It hasn't been completely solved, yet, but an explanation and partial solution can be found in this Wowhead guide.

While the Anniversary is still running, you need to at least complete Azeroth's Greatest Detective to begin your journey. We're not yet sure how much of the felcycle's quest chain will still be accessible once the Anniversary is over, but we know that meta-achievement definitely won't be.
