Growing up and playing the original Hero Quest and AD&D, one of my favorite settings was Dargonlance.
One character that always intrigued me was Lord Soth, the, as far as I'm aware, first ever Death Knight.
I was considering a way to bring this character over as the main bad guy in a possible quest pack, but then I had an idea.
The players rescue Sir Ragnar early in the main system quests, then he's really heard of again.
What if the torture and trauma he experienced before the heroes rescued him left far deeper scars than what anyone could expect
My plan is to make a quest pack with a minimum of 12 quests.
Quests 1 -6 will be the heroes approached by Sir Ragnar and asked to retrieve something or go after a specific target
Quests 7-9 will be a heroes captured and need to escape series of linked quests.
Quests 10-12+ will be the big twist and battle the final boss.
Everything is in my head right now and I will start work on actual writing and quest mapping within the next couple days.
