The Queen Bitch of Fairweather herself, Happy Smiles. Never has a town had a bartender with a filthier mouth! After an accident involving trying to deepthroat a flamethrower her once beautiful voice was ruined and her hindlegs burned off with the rest of her body covered in horrible burn scars. At least if you hear her telling the story.
 
Ponies who know her better suspect her ‘accident’ might have involved her prior life as the heroine ‘Sunburst’ , known for many things including slaying the Mutilator Raider Clan.
 
When DJ-PON3 talks of fallen heroes and those who came before the Lightbringer arrived on the scene she’s talking about ponies like Smiles. For most who embark on the same journey as Littlepip this is how they end up, burned out cripples or rotting corpses in the wasteland.  
Smiles was that naive once upon a time and she’d have plenty to teach young upstarts who think they alone can fix the wasteland.  
She’s left her hero days in the past and although nostalgia sometimes strikes she’s happy where she is now too: Being the most filthy mouthed bartender this side of the wasteland and an alchemist who most know not to fuck with if they value their dignity and/or life.(Based on two different bases. Unfortunately I lost the original files so can’t credit the authors of said bases, sadly enough. Anyone who recognice them I’d be happy to know so I can add them in the description)
