Err, I really don't think unicorn poo is going to be any more special than rat poo.
Neither do I... It isn't like they eat rainbows and crystal
We also don't have the technology to extract hormones from unicorns in the medeival ages.
just because they don't eat crystal and rainbows doesn't mean they wouldn't poop some.
I mean spiders eat protein-rich food in optimal conditions to produce webs, and cows eat grass to produce milk.
Are you suggesting that unicorns eat raw silica and photons, then digest them into crystal and rainbows?
I once made some white chocolate fudge to take to a party, and added to it raspberry extract, a splash of Chambord, and, in retrospect, way too much food coloring. The resulting pink goo was quickly dubbed "Unicorn Poop." It was almost sickly sweet and left mostly untouched until, near the end of the party, someone discovered that it was DELICIOUS on snickerdoodles.
Regarding dwarven culture and analagous human cultures: I know that the usual tendency is to portray dwarves as stereotypical Norse (they mainly originated in Norse mythology, at least as we know them) or stereotypical Scots (thanks to... Warhammer, maybe?), but for a long while I have thought of them more as medieval Jewish, largely due to my second reading of
Lord of the Rings. They're somewhat secretive, keep to themselves, have their own customs, speak their own language which isn't taught to outsiders, dress in different clothing, tend to have beards, are seen as good with money and somewhat miserly, and are skilled craftsmen. Er, craftsdwarves.
Pratchett's descriptions of the Low Dwarves in Discworld has certainly reinforced this interpretation.
