EXEC SEED

EXEC_SEED/. was a Song that initiated the execution of the ill-fated Moocheriel Project. It was intended to draw energy from Ar Ciel in order to turn the Singer, Mihoshi, into a Heart of the Land. That Heart would then serve as the power source needed to complete the construction of Tilia's Tower.

However, angered by the draining of Her scarce remaining energy, Ar Ciel created the Will Ar Ru. Ar Ru then proceeded to use Mihoshi's Heart of the Land to generate vast amounts of Antibodies. Mihoshi's Heart was completely drained by Ar Ru's actions, and so Tilia's Tower remained incomplete.
