Yes, it's fake. I'm the creator of the joke.
It was made for the "Día de los santos inocentes" which is more or less the same as the April Fools day but in the Latino countries and it's celebrated on december 28th, so be careful with what you read on that day coming from spanish speaking countries (Colombia FC posted that Harris had COVID-19, just to put another example).
Explaining a little: First we thought of a concept that Maiden had not explored yet and Eddie being a sea-monster of the depths caught our attention.
I mounted Eddie's face on that Magic - The Gathering artwork, flipped horizontally the image and changed the color palette and worked on an icon with the crossed weapons like in the last three albums (yes, I know I'm not Derek Riggs, don't worry). Then together with my friends of
MaidenArg: Iron Maiden Argentina we thought about some titles that could work for Maiden songs. When the WOTW grafiti rumour appeared, it was like the icing on the cake, so we thought of an album title using those initials. We shuffled names like "War of the Worlds", "Whispers on the Wind", "Weaver of Tidal Wrath" and such. It was like "Majesty of Gaia" but in 2020. We also clarified that it was a joke later saying "que la inocencia te valga", which is the common "blessing" after fall into the joke.
As for the typos, the news was written in spanish only, so the article posted above was translated by somebody else, probably using a translator.
However, we never thought the joke would reach so many fans, which is funny now to see. But at the same time, hope nobody took this as anything else than what it was: a plain joke. However, I liked the idea of Eddie as a Sea monster (come on! he even has morphed into a cloud once, so, why not?)
Cheers! Up the Irons!
