MojoKid writes: There's a subtle yet interesting Easter egg in Fallout 4 that suggests the apocalyptic wasteland has something in common with Bethesda's other popular video game franchise, The Elder Scrolls, the most recent of which is Skyrim. The link between the two comes down to a mysterious plant in Fallout 4. You may have discovered this if you've allied yourself with the Brotherhood of Steel. For those that haven't, the plant in question resides at the research station on the Prydwen, a modified and heavily armored airship owned by the Brotherhood of Steel. There are many different flora, fauna, and animals in the research station, but the one that links Fallout 4 to Skyrim is an experimental plant that looks a lot like the Nirnroot in The Elder Scrolls series. Consider the implication of the plant's discovery in Fallout 4. If it is indeed the same as the Nirnroot in The Elder Scrolls, then not only are the two worlds the same one, but it suggests The Elder Scrolls is actually set in the future even though Fallout 4 appears to have more advanced technology. Suddenly all those beast species in The Elder scrolls like the Argonians (lizards) and Khajiit (cats) may make sense.
