The soul energy within an Umbral Body is incredibly weak.
While this doesn't affect much during life, after death, in order to keep her soul from dissipating, Elara has to constantly feed on the souls of others.
For years, she's relied on Magnus to back her up.
To maintain her soul's integrity, she's consumed countless spirits, not even knowing how many at this point.
The luckier spirits, after being partially consumed, barely manage to survive, though they're left severely damaged and unable to recover.
The less fortunate ones, however, are completely obliterated, their souls scattered beyond any hope of reincarnation.
This time, the whole marriage proposal and wedding ceremony was just a front. Elara's real goal was to find someone whose soul she could feed on for a long time.
But she never expected…
"What? How is this possible? My soul energy… it's draining away!"
