This page offers a guide on where to locate and how to complete the Aqueduct Anomaly, which is a Mystery located in Oxenefordscire, AC Valhalla.
Repair the Animus Anomaly
This anomaly is located southwest of Saint Albanes Abbey. When you interact with it, a glitchy parkour course will reveal itself, and you’ll need to make your way along it to reach the top so you can repair the loose data package that’s creating the anomaly.
First off, you’ll need to head along the aqueduct ruin towards the anomaly course. Then, head down onto the course on the right until you reach the Draggable Reflector. You can move the reflector to redirect a light beam passing through it. You’ll need to move it to the otherside of the platform so that the light beam hits another unstabilised structure. After you’ve done that, you’ll be able to head across the blocks that go underneath the aqueduct, then follow it all the way up onto the higher platform on the left.
On this platform you’ll find two more draggable reflectors. One will reflect the light towards the course, and the other will deflect light beams away from the course. You can see a dim preview of where the redirected beam will go if a light was passing through it, so you can use this to distinguish between the two reflectors. You’ll want to move the reflector with the beam facing away from the course forwards until you reach the light beam - try not to move it sideways, just forwards.
After you’ve positioned that one, move the other reflector into the second light beam, this will cause it the light to shoot back towards the main course, hitting the unstable structure near the ramp.
Now that you’ve dealt with those reflectors, you’ll need to head back down onto the blocks that head beneath the aqueduct. Then, reposition the first reflector back to where it was originally and the light will shine onto the second unstabilised block in the main parkour course. You can then head back up onto the aqueduct and make your way across the course.
After a short while, you’ll come across some Hazards. If you get hit by a hazard, it’ll cause you to desynchronize and you’ll need to begin from a previous checkpoint. The last section of the course has a fair few hazards, but you’ll just need to time your jumps across the hazards until you reach the loose data package at the end and fix the anomaly.
