This quest only begins if the Warden is a male dwarf from the Dwarf Noble Origin and had relations with Mardy during the origin story. It also appears even if the Warden chose to sleep with both Mardy and Teli.
You encounter Mardy when you return to Orzammar. Because of your exile, the child she bore you is now considered casteless. It's up to you to restore the child's birthright. Furthermore, the Warden may also elect to give Mardy some money in order to properly accommodate herself and their son until the election is settled. By choosing that option you can give her 1 , 10 , 50, or 1000.
During Orzammar's main quest talk to either Prince Bhelen or Lord Harrowmont and ask them to accept the child into their House. You can only do this before either one of them is made King (or shortly afterwards), else the child will remain a casteless dwarf.
Your illegitimate son regains his status in the royal house -or- your son remains casteless. If he regains his status, you are given the chance to name him. Amongst the names you can choose are 'Endrin', 'Trian', 'Duncan', 'Gorim' or after the Dwarf Noble Warden. If you let Mardy decide, she will name him Endrin. The name 'Trian' will not be an available option if you killed him during A Noble Expedition.
- If the Dwarf Noble had accepted the noble hunters' proposition (only possible as a male), Gorim Saelac during A Noble Expedition, will have some remarks about it which would vary whether Mardy joined the Dwarf Noble or both Mardy and Teli.
- Bhelen will refer to Mardy as casteless, even though she appears to lack the brand.
- Naming your child through the Mardy dialogue grants you 100 XP, and can be repeated over and over.
- This quest is meant only for male Dwarf Noble Warden characters, but appears in every player's codex as a failed quest after completing A Paragon of Her Kind. As of patch 1.04, it is impossible to successfully complete this quest, even if you are playing as a male Dwarf Noble. Examining the quest in the toolset reveals that the quest is marked as failed as soon as a king is crowned. No references to race, origin, or plot flags are made.
