“Country Mouse” used to run with a sketchy thieves guild in his past. He owed a lot of money to the Whispering Wind. He died when facing the Cragmaw goblins. His only friend was Keth. After his death his ghost would often use Lucien’s telepathy powers to talk to Keth. He accepted as the proper “inheritor” of Keth’s name if he wishes to use it and that Keth would be proud of his now “heroic” persona.
