And Chirurgeon going for the fast burn rather than the more conservative matrioska approach, which I guess makes sense when you have effectively infinite versions of the star to play with.
Now if it wants to change system it can now relativistically slowboat via Antimatter Photon Rocket with a ramscoop, unless it has a reactionless drive design stashed in that crystal somewhere. I doubt regular shards are given access to the shard FTL method tbh, and would it even work in this reality?
Tho ofc that would immediately make her prescence obvious to the neighbors, tho its probably too late given how distinct antimatter is. Just gotta wait for the light emissions to reach our funny aliens
