Carl Szoke got stuck paying off someone else debt after he died, due to someone in charge screwing up.
But they still needed someone to build and run the Fighter Tutorial Dungeon and if Carl didn't do it, he would just get stuck working some other job that no one else wanted.
So after a brief, very brief set of instructions, they left him to it.
It being getting the Dungeon ready for the ten thousand trainees waiting for their turn to go through his dungeon and unlock their class.
Only Carl does things his own way and he wants to give people as many options as the system has available.
As well as some that it doesn't.
Like limiting himself to only being in the Dungeon.
Notes:
Book one is finished, Book two will be started after I have a good go at editing Book one.
Also, the hyphens suggested by Grammarly seemed rather excessive so for the most part I'm just skipping on using them. Apologies if their lack is jarring you out of the narrative.
