My dm made an amazing NPC from my background

So we are playing in a homebrew setting (5e) in which there is an authorative state religion but still some pagan traditions in the forgotten corners of the land, which my paladin hails from. In my background I explained how my paladin has a sister who works as a steward in their family home as they are waiting for the heir to come of age. Pagan faith is forbidden, so the family has stayed out of national politics. As I handed over my background a said something like ”who knows, maybe the sister will abandon their family traditions in favor for power” just in passing and boy did my DM deliver. She has crafted an amazing character that is torned between ambition, duty, tradition, faith and family. She feels like a character from Shakespeare or a greek tragedy. This game is amazing.

Now that I’be got this out of my system, why dont you share your amazing NPCs
