A lot of people are saying Spark killed Dianite but the problem is dianite was killed after Spark left.
Spark, Jeremiah, Country Bat and Mot left and caused Ianite to go into depression which caused the taint that killed Helgrinds wife and daughter. This is what cause Helgrind to pray to mianite for vengence. Mianite used that as an excuse to reap the power he craved but Diantie was preventing him from killing Ianite so Mianite had an assassin kill Dianite which lead Ianite to flee to her home in the end.
