Well they have info and the first are covered even more in Stardust Sapphire which focuses on one named Laleh and her people. Also I don't see why its a problem to have them when they're relevant and have official names and info while there are articles for every single camel in King of Thieves which I don't think were actually officially named.
Also is it okay to add full pages from the books? Won't that get the wiki hit with a cease and desist notice or is it alright to upload them as long as the pages are low resolution? If so I'll try and start uploading the full pages for book articles if that's legal.
