6 Harry Potter and the Dreemurr in Need » by MaxieProdmoore My take on TheZorker's Harry Potter and the Underground's Saviour. I'll definitely do my best to have it evolve to be truly my take on a Post Pacifist Run meets the Harry Potter 'verse as of Prisoner of Azkaban. Will contain scenes that lean towards the film's interpretation of events. Lastly, Frisk in this tale is male, Eurasian and has Dyspraxia.
