Very good! I really enjoyed the story. You ask for comments, so I'll give you my views on it:
1. The original mixture of Empire fluff and Greek mythology is working very, very well. As a source of inspiration, you probably have a goldmine here.
2. English is not my first language, but as far as I can tell, you are a skilled writer. I very rarely have to re-read a section to get a grip of it. No typos I think! Also, a lot of humour shining through, even though I may have missed a pun or two due to language.
3. Formatting: I think it is commonly advised that italics should be avoided in longer texts, for maximum reader-friendliness. But I understand that your italics signifies letter-writing. Is it, by the way, possible to attach .pdf files to posts here?
4. The burlesque humour: Great ingredient in your story. Matter of taste, but I think that you could achieve even greater comical effects by toning it down just one notch. I would say that the hint on the Pektoral warriors' "choice of lifestyle" is at the right level, while the passage about the "anthropological investigation" of the twins is almost too obvious.
5. Give Valter a personality trait or two! Whining, sour, snobbish, laid back, confused, smug et c. That way, if you continue your writing (please do!), your readers will get the feeling that they get to know him.
6. This is great, keep writing, whatever you do! I am proud to have contributed, if ever so little, to you posting this! Thanks!
