Mohe wanted Lisidorwei dead, of course, this plan would require delicate handling. Any slight misstep could lead to Doro turning against her. Thus, while the intention was there, Mohe had to ensure that none of it could be traced back to her.
Even that wasn't enough, for anyone losing their cool would risk blaming those around them. Mohe needed to act as if she tried her best but couldn't save Lisidorwei, allowing Doro to wallow in his grief over Lisidorwei's death and thus further his resentment toward humans.
And who was the main culprit? Naturally, it was Saintess Charlette and her reinforcements~
Therefore, noticing everyone else had begun gathering materials to craft the gargoyles at Lisidorwei's behest, Mohe decided to attack Doro in the dead of night.
