What remains is the OT, which has been answered. Klyros are not dragons. Yes, they have wings and scales. However, not even close to all dragons do have wings or scales. There are so many different concepts of \"dragon\" out there, and not all of them are compatible. For example, eastern traditions will see no resemblance between Klyros and dragons whatsoever, because their dragon concept is quite different, and it\'s not the only one that is. And there are concepts that have elemental dragons, others that don\'t, so saying \"dragons don\'t like water\" is valid only in the context of a few of the existing concepts.
Klyros have been used for all sorts of argumentations, like comparing them to gargoyles to justify angels, which AFAICS is a lot closer than dragons, though also not precise, since gargoyles are more similar to dragons than are Klyros. In fact, the mentioned depiction of humaniod dragons is IMO so far off the actual dragon concept that is being referred to here that it\'s not even valid to talk about dragons anymore.
I think this is mostly due to the fact that the mentioned races (Klyros, Enkis) are a lot less common in fantasy worlds than others like elves and dwarves. Similar, in fact, to the creatures they are being compared to (dragons, gargoyles), which also are (usually) not a common siht in the fantasy worlds they exist in. This is the greatest similarity IMO.
The point is that there are some properties they share with some of the major concepts of dragons (whereas Enkis have similarities with almost all existing cats), but the overall number of similarities is very small, they just stick out because one looks closer at them since they are not so well known.
What I have noticed is that Klyros are being compared to just about everything (dragons, gargoyles, demons, fish, birds, bats, lizards whatever) in about the same number of cases, and this IMO proves that they are not dragons (nor any of the others). They are dragons to the the same extent to which they are humans: a tiny bit only.
Thus, I agree with the OP: Klyros look similar to what may be increasingly classified as \"dragon\", but in fact is nothing but a humanoid lizard. However, this concept is not what a dragon traditonally is, and thus is, at best, a \"new\" concept that is quite incompatible with the others. Therefore, it can not be used to argue against the \"no dragons\" statement of PS, as it clearly refers to the traditional concepts of \"dragon\", not the (IMO diluted and misguided) concept of IMO \"non-dragons\".
