Whether they were asleep or awake when sealed by the Dwarf Vein Sealing Technique, the Giant slaves all appeared extremely aged, yet their bodies showed no signs of decay.
Their manner of death is quite mysterious.
It can be seen as, when the Dwarf Vein Sealing Technique was successfully executed, they were effectively killed at that moment.
Alternatively, it can be viewed that they collectively aged rapidly to death the moment Giharin lifted the seal, with their flesh showing only a façade. The Giant children among them certainly wouldn't grow up and die of old age in a mere instant; this kind of time reversal affects more the soul.
Those without a soul or having eternal life, like the Stone Spike, were not influenced whatsoever; everything about them, including memories, stayed as it was at the moment of the sealing.
