In that new story, he has his MC being slow due to the two treasure chests he is carrying, being 200 stone
A stone is 14 pounds. 200 times 14 is 2800 pounds.
Those 14 pounds is modern time UK/Imperial weight.
During the ages, the weight of a stone was widely different, depending on location, commodity and time. Even in England a stone of 5 pounds was used for glass, an 8 lb stone for beeswax, pepper, meat,... a 12 lb stone for lead and a 14 lb stone for live animals, and wool was weighted with stones of 14, 15 and 24 lb.
In East-Prussia (now Poland and Russia) they differentiated between a large stone of 33 local pounds = 15.444 kg and a small stone of 22 local pounds = 10.296 kg.
Because Shadow is a fantasy story and a stone there may have any weight, not related to historical or modern Earth weights, I assumed the 200 stones were a typo and should read 20 stones. Assuming the British 5 lb stone for glass or the 8 lb stone for spices and meat then gives a total weight for the chests of 100 or 160 pounds.
An indication that the stones in the story are not the UK weight unit, is the use of the plural stones, plural for the British unit is stone (no plural 's'!).
