"Hee hee hee! Why the tower of the evil enchantress, of course! I mean, I was working for her at the time, sort of- I needed to join her Order of No Quarter to collect the essences from the different knights of the land, you see! To brew the ultimate potion, the Serum Supernus!"

Plague Knight rubs his hands together again, and there's the distinct impression that he's grinning behind his mask, "I discovered I didn't need the potion after all, once I brewed it... But there was enough energy in it to blow up the tower in such a beautiful display that it could be seen across the whole Valley! Hahaha! And you know what they say- the bigger the explosion, the better the alchemist!"
