Emizel is going to be more affected by demon instincts that night, and will be up to general not so good while the moon is in effect. He will be more hostile and looking for ways to cause disasters, mischief, or basically ruin anyone's day if left to his own devices long enough.

Others are welcomed to fight or try to contain him if they like (Beware though, he is a death god with a legit scythe. Also has a monstrous form). Or any other plot ideas are welcomed here or Grifstar
