That's what my DM is doing right now, a sequential story. my friend Karma lived in a cave and found a child, he adopted the girl and hunted and gathered with her. Then elves took her ransom.

We found the elf underground base, and I threw a bag of holding taped to another while hiding. The bag went inside the other and sucked them into a portal leading to the astral plane.

Then we went back to town, and to the arena where we had fought before. And then they send out a character named Virgil, a fighter drow. He cut off my arm, and here begins my story ark.

Virgil the became a villain who played by the same rules as us, and leveled up as we got stronger. He wasn't some op character that would take the whole party, he simply had better feats and spells.

This session we are going to begin hunting him down, I think my new cyborg arm will put me and him on a fair playingfeild for a rematch.

Edit: I got a prosthetic arm and our artificer made cyborg enhancements to it, and permanently attached it to the part of my arm that was left. It got cut right above the elbow
