So, in this page you can share any new villian (like malistaire and Morganthe) you may like added to the spiral. I think a shadow may be good who transforms into a wraith during the final battle with him.
I have been thinking about the book of lost pages event and maybe a new villain could be the Scirbe he is the one who created the spellwrit creatures. Also you could make grimore wands a thing. Such as maybe a spellwrit spell book that gives a "summon spellwrit snowman" The world could be filled with spellwrit enemies.
