I thought it was, but couldn't find any evidence to support that.
Perhaps you could explain a bit why?
IC non-guaranteed-as-true fluff:
The Immortal Kings invested a fair bit of power into making an everlasting tech lock that prevents the world from ever progressing into the Industrial Revolution. To that end, the denizens of Altera will never have the inspiration or idea to create the printing press or a number of other technologies that would kick off the Industrial Revolution, because the lock prevents them from wanting to invent it.
OOC:
The server is meant to take place around the Renaissance, maybe a bit after. People love snowflaking it up and will invent technologies that exist IRL without knowing how they actually work in order to make their character a special inventor or notable or whatever, and even if nobody specifically has the intent to move the server timeline forward, enough people doing it will warp what we've got to some steampunk nonsense that isn't regulated as tightly as the current lore and then it's a whole mess to clean it up and push things back to a reasonable condition. It's happened before in a different direction, the 2012 HW mess of high fantasy, powergaming, metagaming, and rampant
terrible roleplay with orphan assassins all over the place was the result of not keeping things regulated to prevent a slow slide into that molasses, and the loreteam ended up having to invent a
series of campaigns to push the server back to low fantasy and had to tighten the rules a lot, leading to people mad that their character was being changed, people mad that airships were going away, people mad they couldn't do X because the new lore forbade it, and so on. The shift back alienated a lot of people and we rode through early-mid 2013 with a historical low player count until it started replenishing when the Negative Nancys finally left and the server stabilized to where it is now.
Hell, there's still cleaning going on now,
three years later, because it was such a huge mess. Before she left, Mich was reworking a bunch of lore. We still don't have a concrete IC reason for why the airships are gone (besides, y'know, physics, since not one of those things should've been able to fly).
