The Mastodon Colossus, or Hotel Elephantine, was built as a tourist attraction on Lapin Isle in the City’s barony of Rook End. The (admittedly eccentric) architect Jamis Maguffin constructed it through consultation of certain codices of the Ancients--and some magical materials probably dating to Meropis dredged from the City’s harbor. The elephant was twelve stories tall and had stout legs 60 feet in diameter. It had 31 guest rooms, a gallery, tobacconist's shop, and an observation deck shaped like a gigantic howdah.
Most spectacularly, the whole thing was planned to move. Maguffin promised that when all of the thaumaturgic glyphs and enhancements were complete, the elephant would be able to ambulate without any seeming change to the rooms on its interior. These enhancements, unfortunately, would take some time.
Eleven years later, when the thaumaturgical working was (supposedly) nearly complete, the elephant walked away one night with a compliment of guests. Most have turned up dead in various locales all over the world and beyond in the four decades since.
This post first appeared in February of 2011. I did a post on the real elephant-shaped buildings of our world after it. You can also read more about them at your local library. Or, you know, the internet.
