At the top floor of Chen Yu's Mage Tower, the Obsidian Altar he had used initially had already been moved here.
This altar was originally designed and crafted for the construction of the Necromantic Space. After Chen Yu's use, it was rendered useless and thus had been left to lie idle.
The only reason it hadn't been dismantled was that Chen Yu intended to leave it for Jounouchi Hiromi, so when she was ready to build her own Necromantic Space, she wouldn't need to make another one.
But now, Jounouchi Hiromi had become his wife, and as husband and wife were one, Jounouchi Hiromi no longer had the need to construct another Necromantic Space, so the altar remained unused.
It was only now, with Misumi Mikoto as Chen Yu's disciple preparing to construct her own Necromantic Space, that the altar Chen Yu had spent a great deal of effort creating, once again became useful.
