Inhumi eyes and names

This is the message as the crawl holds it, before anything here touched it. What the conversation shows has been through ingest: transfer encodings decoded, attachments dropped, quote markers repaired, and the archiver’s ? resolved into quotation marks and dashes. Those repairs are judgements and some of them are wrong, which is what this page is for. Email addresses are obscured here as they are everywhere else on the site, so it is before our repairs rather than byte for byte.

Therefore infrared should be scattered even less.  A being that could see only in the infrared, and maybe not the near infrared, would be able to see the sun, but the sky would look black to him or her.  I can't think of why such a creature wouldn't be able to see the stars.

That too. But I had not thought (not being a physicist) of scattering, 
which helps to obscure the stars for us. But wouldn't stars themselves 
tend not to emit infrared visible over interstellar distances?
