In the final page of" Majesty and the Old Hermit Crab", the former turns an old hermit crab into the Cancer constellation (we later see this crab again while Locket is flying through the Milky Way galaxy)
First, let's calculate the speed of the crab being sent into the stars.
The Cancer constellation is 590 light-years away, and it happens pretty quickly, so:
590 light-years per 5 seconds = 1.11634235e18 m/s (3.72371726e9c, MFTL+)
590 light-years per 10 seconds = 5.58171176e17 m/s (1.86185863e9c, MFTL+)
590 light-years per 15 seconds = 3.72114117e17 m/s (1.24123909e9, MFTL+)
However, the Cancer constellation also contains the barred spiral galaxy NGC 2608 which is 28.5 megaparsecs away.
28.5 megaparsecs per 5 seconds = 1.75883622e23 m / s (5.86684612e14c, MFTL+)
28.5 megaparsecs per 10 seconds = 8.79418111e22 m / s (2.93342306e14c, MFTL+)
28.5 megaparsecs per 15 seconds = 5.8627874e22 m / s (1.95561537e14c, MFTL+)
Now the creation of the constellation:
Cancer, through the spiral galaxy NGC 2775, contains at least 100 billion stars.
5.693e41J (Sun's GBE) x 100000000000 = 5.69300e52 joules (569.3 MegaFoe, Solar System level)
Hm, I expected higher, but maybe, given this page's "If a whole Galaxy is moved at FTL speed, the feat will be ranked as Galaxy level", this could count as Galaxy level?
Let's find LS as well too while we're at it: Solar mass of 1.98900e30 kg x 100000000000 = 1.98900e41 kilograms (expectedly Multi-Stellar)
This would scale to both Majesty and Cancer
Creating the NGC 2775 and NGC 2608 galaxies[]
The former has a diameter of 70000 light-years while the latter's 62000 light-years.
I can't find how far the farthest star in these galaxies are (most are unnamed), so I'll halve the distance.
I'll just use the same formula as what we have here, but with the average star distance being changed to half the distance between Earth and NGC 2608 and NGC 2775, 4.39709055e23 m and 3.16927702e23 m
4*5.693e41*(4.39709055e23/695510000)^2 = 9.101757e71 J
4*5.693e41*(3.16927702e23/695510000)^2 = 4.72840667e71 J
4.72840667e71 + 9.101757e71 = 1.38301637e72 J (Multi-Galaxy level)
