What does Weyland do? Judging by the word used in all three of the Weyland Consortium's current megacorp identities, it's build. Weyland builds nations. Weyland builds a better world. Weyland built it.
This is why Weyland uses advancement tokens so much. It's not just construction projects like Oaktown Renovation; even Weyland's ice can be built up. With bricks of clay and blocks of code, Weyland is leaving its mark on the world.
So what is Hortum all about? Why is Weyland suddenly interested in digital gardening? Isn't that a little Farmville for Jack Weyland, the man who built the Beanstalk?
Only two other pieces of ice have Hortum's "parenthetical text" ability, and looking at them reveals what Weyland's building. Mausolus is a tomb... or mausoleum. Colossus calls to mind a certain giant statue from antiquity. Hortum here has a name that means "garden" in Latin (which you might recognize from English words like horticulture).
The Weyland Consortium is paying homage to the seven wonders of the ancient world. Mausolus is the Mausoleum at Halicarnassus. Colossus is the Colossus of Rhodes. And Hortum? The Hanging Gardens of Babylon.
Could there be a more perfect theme for Weyland? A megacorp all about building, about wonder and expanding the horizon, tips its hat to some of the great dreamers and builders of eras past. The architects of antiquity had the audacity to aspire to greatness and do what seemed impossible. No doubt, Jack Weyland sees himself in the builders of yore.
At the time of this writing, there are four wonders left unrepresented: the Great Pyramid of Giza, the Statue of Zeus at Olympia, the Temple of Athena, and the Lighthouse of Alexandria. Weyland's not the type to leave a job unfinished. I expect to see these Seven Wonders ice rounded off in packs to come.
