There's some really evocative imagery, characters, and lore to this piece, unfinished though it may be. I hope you keep working on it and fleshing it out! The biggest challenge with it (besides missing parts) is just the writing. The title could use a slight grammar tweak: maybe "Beyond Curtains of Rain" or "Beyond the Curtain of Rain"?

Thanks a lot, I will definitely develop it further. As you probably noticed I've tried to write in slogans rather than in full sentences, since it is easier to navigate during session and I'm not as much fluent in English as I would like to. Some parts of scenario were in fact cut off, and I hope to add them when I figure them out.
