Assassin's Creed Valhalla players that want to complete all of the Meath Mysteries will need to make a suitable offering to an altar in Rathbride. More specifically, they will need to hand over five Sturgeon (big), though exactly where this fish can be found may not be immediately obvious. Fortunately, there are a number of suitable locations for catching Sturgeon (big) in Assassin's Creed Valhalla, and this guide will highlight several spots that players can visit.
To note, this guide will assume that readers already have a solid understanding of the game's fishing system. As such, fans will not find details on how to obtain a fishing line or how to use one to catch fish in what follows. Indeed, it seems unlikely that a player will have reached the Wrath of the Druids DLC without knowing how to fish in AC Valhalla, and it is thus the locations where Sturgeon (big) can be found that will be focused on.
With that established, the most convenient place to fish for Sturgeon (big) is perhaps the Liffey River, which runs just to the north of Rathbride. While it is possible that the relevant fish can be pulled out of every section of this waterway, they seem to appear in relative abundance near the border between Meath and Dublin. Assassin's Creed Valhalla players are thus advised to start fishing there, and they can work their way slowly west if they need to.
Alternatively, fans can fish for Sturgeon (big) off the south coast of England if that is there preference. The parts of the ocean that are in the Cent and Suthsexe regions in particular appear to be home to quite a number of these creatures, and fans may want to focus the bulk of their efforts on those spots. While there is not a great deal of incentive for catching Sturgeon (big) away from Ireland in AC Valhalla, it is indeed possible to do so.
After obtaining five of these fish, players should return to the Rathbridge altar and interact with it to make the offering. When that is done, fans will receive indication that they have completed a Mystery in Assassin's Creed Valhalla, though this is certainly not the only one to be found in Meath. In fact, there are a total of four Mysteries in this region, and the others center around completing Trials of the Morrigan and solving a cairn.
Assassin's Creed Valhalla is available now on PC, PlayStation 4, PlayStation 5, Stadia, Xbox One, and Xbox Series X/S.
