I still don't think it belongs in game, for a variety of reasons that I'm a little too tired to list.
What you think belongs in the game does not equate to what does belong in the game.
Something that many players over the years often don't comprehend is that the game was never created with realism as it's core foundation. The game was created to be
fun and
entertaining, a place for players to congregate that was different from the other MUDs out there. What you have
now, no matter how shiny the bells and whistles have become, is nothing compared to the proverbial wild west days of Armageddon.
Where before you had true brutality, in no small part because many players were left unchecked and free to stomp around and behave like the barbarians we all are deep down inside, you now have carefully refined and manicured pretension. A game staffed by people more interested in perpetuating their own egos and the illusion of power they (often, but not always) lack in their real lives. It takes role-play to an entirely new level, doesn't it?
You say it doesn't belong in game. Why do you think so?
The Zalanthas you have is the end game, the last desperate, dying days of a once vibrant, living planet, brought to a strangled end by the very nature of the beings it once nurtured. The Known World is a shattered sliver of that planet, where the game takes place, but is not the entirety of the world. The game world you experience has been has been retconned again and a gain with the changing of hands and endured two radical changes in administration.
The history of the Known World and the world at large is no longer even relevant to what the game is today, but there is an extensive amount of lore behind the game and all that happened before Armageddon opened it's doors. In that history, entire empires were created and annihilated and in it's golden age, people were much more advanced and resources, such as metals, and knowledge, such as metallurgy, were far more refined and common.
The city-states you have now were raised from the shattered, tribal remains of the last (and prior to some bastardizations, "evil") empire, with one them founded by a line of men who amount to being the greatest frauds in human history; using power from the last empire and passing it off as their own. The other was created on a sketchy basis from the onset and has been so muddled by retcons and changes (including a change to red hair, of all things) that it's no surprise it continues to spiral further and further away from the original spirit of the game.
With that sitting in your lap now, does it seem so improbable for those of fabulous wealth, peerless education and limitless reach to have acquired both the materials and knowledge to have such a thing constructed? Or to have one of the many virtual tombs and ruins of past civilizations delved, looted and their treasures restored?
What you have is a game that has become so progressively watered down, diluted and tamed that it no longer even resembles it's original dream. That you can't imagine a place for it isn't a fault of your own, or a flaw in the game, but rather a symptom of the games degradation over the years. A clock, should it or others even still exist, is not just possible but far more likely to exist based on the often ignored lore of the game.
You have vinyl lookalike halter tops, platform heels, hot pants and countless other imports from modern Earth, movies, video games. There is a sword in the game that is the text version of Frostmourne. None of these things raise an eyebrow, be it here, the GDB or in the game proper.
A clock rescued or re-created by an NPC of great importance is completely within the bounds of lore, yet it's the hot red short shorts with ivory buttons and tassels gets an unblinking pass. That is the state of the game, today.
That doesn't really make physical sense or match the method of acquiring said obsidian, so I never took that too seriously.
I don't mean to repeat myself, but the game was never created with real world realism -or- extreme realism in mind. It was created with the idea of designing a unique and fun experience for players, but that vision has changed from person to person and administration to administration. The inconsistencies you see in the game are a result of deviation in direction and different interpretations of the lore, followed by re-re-interpretations, for twenty plus years.
Take it as fact: Obsidian in Zalanthas is both more durable and more difficult to place an edge on than Earth obsidian. You don't need to like or agree with it, but that is how it is and is reflected (or was) in the code. The steel sword that was taken from dead Templar "Hrm" by the fallen Yasania her lover Talia (or something similar) the Mek on the tail of the overthrow of Allanaki forces in Tuluk, the source of so much drama both in the game and between players, did no more damage than an obsidian shortsword sold in Allanak for a handful of coins.
A bit of trivia: Wood is also considered to be much denser and durable than on Earth. With appropriate treatment (fire), a wooden sword should be close to as durable as a bone sword and both lighter and sharper, but to my knowledge this is not reflected by the code and one of the reasons many people north and south spurn wooden equipment in favor of alternatives that are by code, far superior.
