Courting gone wrong
I am looking for this fic that I've read on ao3 and want to read it again but I forgot the title :/ It was: completed, bagginshield, there was a self proclaimed king who was a dwarf that didn't leave Erebor during dragon's attack and remained in the shadows and became twisted, during meal Bilbo challenges Thorin to find him/catch him not knowing it is a dwarf courting tradition to give a challenge to another. So yeah that's it - thanks in advance if someone remembers the title :)
