Does... does this implies that... Chilchuck is the tallest of them all...? If they were all haflings, it's oficial that yes. Now, look at me play my game.
Chilchuck is said to be tall for a hafling, and he is. The avarage would be 100 cms, and he's 110 Laios is a tallman, but he's also tall for his race (the average height is 180cm for men, he's 185).
Marcille is 160 (elves are 150 and tall men 170, so we good here, I'd say she's average too). Sehshi is 140, he's actually taller than the average for male dwarves (135). And Itzusumi is shorter than the avatage of female tallmen (170), being only 150.
So far, if they all changed to the same race at the same time, Itzusumi would always be the shortest, followed my marcille. Senshi and Laios should be around the same height since theyre both 5 cms taller than the avarage (I know that as haflings Laios is taller, maybe he keeps being taller than Senshi just because). And Chilchuck would be the tallest. He's 10 cms taller than the avarage of his race after all.
Might this useless information hunt you until the end of your days.
