Just like the Demigod behind the Golden Treasure Hall, who back then had a Divine Realm that could continuously produce Legendary-level weapons.
This Semi-Divine Artifact is actually a kind of domain-type existence as well, whose characteristic is that it can continuously produce Undead Soldiers. Moreover, the Undead Soldiers produced from within it do not consume Audrey's Command Value.
Theoretically, as long as Audrey invests enough Undead Army units into it, then in future wars it'll be enough to rely on the Ghost Army produced by the Semi-Divine Artifact.
She can go full Summoning Stream, fighting wars purely through Summoned Creatures without using up her own foundations.
