so i had a dream where a group and i were magically summoning like, liquid stone and by-hand forming it into walls--this is clearly half-baked and inefficient--so how would YOU make or enhance construction processes using magic, sci-fi technology, or fictional materials?
In the setting I'm working on, one of the ancient elven technologies they reverse-engineered is something they call "gossamer looms." Gossamer is the name given to the rose-colored threads of ethereal pseudo-matter that can be arranged in any shape imaginable to serve as the framework for fusing materials together. It's frequently combined with their illusory projection tech (magic mirrors) to do rapid construction with pre-existing templates. Feedstock (typically gravel, sand, sawdust etc) is drawn through a "loom" which can vary in size from handheld to so massive they require multiple levitation engines in order to be used at all. This feedstock shoots along the rose threads of light suspended in air to fuse to whatever template has been drawn in the air, either freehand or pre-recorded.
How exactly do the materials fuse together? Good question. The Mages' Guild is working on that one. But they have more pressing concerns, like the eternal maelstrom of lightning that they're barely containing following that storm bomb during the big war, or how to cleanse that peninsula where every dead thing that falls there rises up and sprints in the direction of the closest living thing to kill it.
i'm imagining this somewhat like a highlight box for placing objects in a game, but integrated into the setting, cool stuff. gravel sand and sawdust don't seem like the most sturdy of materials though, how does it become structurally sound? must it even or can you design a gossamer that immediately collapses
Still figuring those things out tbh but when the material fuses together into a solid object, so the granite dust becomes a solid block of it, sawdust becomes something like hyper-condensed super sturdy particle board etc.
Structurally unsound? You got it. Even a building made of solid stone can collapse under its own weight if the architect is a dipshit.
