"Running, running, I have got to keep running" is all Erebus could think while the small and timid look goblins were chasing him. Having lost his long sword from being overpowered by to many goblins at once, Erebus had no choice but to run. Running out of this beginners dungeon was one of his only choices, knowing that monsters aren't able to leave the dungeons unless certain conditions are met. The other choice being to try to find someone else's party for them to help with the high chance afterwards that they are resentful at Erebus for putting his problems onto other people. Which might lead him getting banned from the dungeons, kicked out of the city, or the worse things is getting put in prison or getting hanged as an example. So he ran, ran straight to the exit.
Inside Erebus's mind was how he was great-full that nobody saw his ridiculous crying, scared little girl, already peed himself face.
Erebus now in the city contemplating about what he is going to do now that he lost his sword. Him not having a lot of money put restrictions on his spending if he wants to eat everyday of the week and have a place to stay. So the only idea a hunter would have is to go back in the dungeon with a tiny, rusted, and old knife he got from a butcher. Who seemed to have some sentimental feelings to the knife but was willing to part from it for only 2 copper.
So after resting for one day Erebus was ready to go into the dungeon to find his sword. With his old rusty knife, and one mini healing potion that was definitely not a good enough potion to heal any big injuries he paid the fee of 1 silver and walked back into the dungeon hoping to find his sword.
As Erebus creeps further down into the dungeon with his tiny knife at the ready, up ahead he notices it. The small frail and weak goblin that he found out that goblins are definitely not weak or frail like he thought.
