Recycled Script: Desoloth a dragon of the prime elements being transformed to Desolich by Drakath after being killed by The Hero is like how Akriloth who is also prime (but is only fire) is killed by The DragonFable Hero and being turned into a Dracolich by Xan.
Speulchure's Origin is similar to Xan's with the 'whole love triangle that makes him evil' part.
Doomwood Saga also involves the Hero finding a way to enter the Necropolis, and once again with help from Zorbak. Although rather than pretending to be a Necromancer, the Hero actually becomes on this time.
Some of the stuff that's been named has been based on crazy ideas. In the Design Notes, Beleen notes that the name of her chinchilla (Chongo) was named that when Cysero—unable to spell chinchilla on Google—decided to called it 'Chongo'.
It's stated that Beleen's chinchilla's name was based on Cysero — having decided to not use Google to figure out how to spell it correctly — and just call it Chongo instead.
What Could Have Been: Interfector Deorum Armor was originally going to be called God Slayer but in response to many players feeling uncomfortable with the name The Staff decided to call it the Interfector Deorum Armor
"Interfector Deorum" is Latin for "Slayer of the Gods," so it still technically has the same name.
