Introduction
Brandish, one of the Spriggans, raises an island several kilometers in the air
Basic values and scaling
First panel
Height of the random person = 1.7 m = 18 px
Height of the ship = 162 px = 15.2999 m
Second panel
Height of the ship = 3 px = 15.2999 m
Width of the island = 588 px = 2998.79804 m
Third panel
Island's width = 2998.79804 m = 218 px
Island's top = 31 px = 426.434 m
Island's height = 90 px = 1238.0358 m
Stone colomn's width = 320 px = 4401.9053 m
Stone colomn's height = 708.935 px = 9752.077 m
Height above sea level = 650 px = 8941.3703 m
Calculation
Volume of the structure = volume of the top island + volume of the colomn
Volume of the top island = volume of a conical frustum
Volume of the top island = 6947690000 m^3
Volume of the colomn = volume of a cylinder
Volume of the colomn = 148411793819.058 m^3
Total volume = 155359483819.05 m^3
Density = 2700 kg/m^3
Mass of the structure = 419470606311459.214 kg
Center of weight of the structure = height/2
Center of weight = 4470.685 m
GPE = m*h*g
GPE = 18391273155616350854.96 joules or 4.3956 gigatons of TNT (Island)
Conclusion
Brandish brings up their world = 4.3956 gigatons of TNT (Island)
Pretty casual feat. Should scale to half a dozen characters
