 The first trait's application is more straightforward - anything where alchemy would be useful, whenever you need to create matter out of the vacuum, whenever you want to turn matter into vacuum, whenever you want to turn energy into something else, or really even just whenever you need a big traditional explosion, the ability of Thread to //convert// is highly useful feature. It can even be used on a very small scale to bio-engineer with high precision.
+===== Prevalence =====
+Sheathed Free Thread is a reasonably plentiful resource in the universe. Unlike Static Thread, it's in constant motion, following wells of gravity. However, unlike Dark or regular matter, it isn't **attracted** by gravity.
+This may seem like a strange assertion - why would something follow gravity wells without being attracted by gravity? The answer lies in a //preference for curvature//. Thread that's 44 000 kilometres removed from some body's centre gravity will (assuming both no changes in the gravity well such as the body getting additional mass from an impact event, but also no nearby bodies manipulating the gravity well of the body) have a preference for remaining exactly 44 000 kilometres removed from the centre of  gravity of that body - no more, no less.
+Note that Thread does little to resist being moved from this point of preference. You can picture it like a single corn of dry rice in a perfectly smooth, semi-spherical bowl - if you let it go, it'll slide back to its point of rest at the exact centre of the bowl, but it's trivial to move and hold to any other point on the bowl. That said, unlike the rice corn, Thread moves at an effectively constant speed to return to its point of preference, and as already mentioned, its point of preference does not coincide with the centre of gravity.
+Once Thread is unsheathed and delivers its payload, its gone - so it's possible to deplete a region of space of (Free) Thread by harvesting/collecting the Thread and/or using it up. There are no current processes in the universe that would create new Thread (the last Thread creation occurred with the cosmic inflation event). That said, there is so much of it that any travelling Threadwielder is unlikely to run out.
+===== Dangers =====
+In theory, it's possible to completely undo the universe with Thread. In practise, the necessary payload would be immense and cryptic. It's unlikely even a dedicated Threadwielder would be able to pull it off, even if they wanted to invest a billion years into the endeavour.
