(Note: While sorcerous intervention of one form another is assumed to have played a part in the history of essentially all beastman species, including the likes of merfolk, in none is the fact so apparent -- or the case so muddled -- as that of serpentfolk. Such insights into their origins as Black Steel personnel have encountered may hint at the means of all beastman origins ... or might be a case of convergence or imitation that only confuses the issue further. It is all but certain that there are human-like beings with serpent features who began life as strictly human entities, and acquired their serpent-like characteristics thanks to the intervention of magical forces directed by entities whom they worshiped ... and who themselves appear in shapes often associated with serpentfolk. Whether this form represents anything more than a reflection of the worshipers' beliefs and mythology, and the extent or nature of such corporeal beings' divinity -- whatever that means -- remains to be seen.)
Black Steel personnel have seen serpentfolk of so many different descriptions within the jungles of Grat'ha alone -- to say nothing of those they encountered in Night Harbor -- that a general description seems impossible. One reason for this -- perhaps among many -- was discovered when Herring and Theril first met Dotrum in the jungles: His own eyes have serpent-like slits instead of pupils, and he said that this was part of a blessing he received from the "jungle gods," as a mark of distinction, so that he would be recgonized for his service to them. The "jungle gods" to whom he refers apparently manifest in the form of serpents or serpentfolk of various descriptions, and convey gifts of serpent-like features upon those of their faithful to whom they give special blessings -- tokens that win their bearers much esteem in Grat'ha, apparently, presumably because it is associated with the form taken by the "jungle gods." Because these gifts are conveyed individually, they tend to be ... individual. Any number of different serpent features have been recorded, from eyes to scales to a tail for legs to an upper body and heads like a multi-headed serpent's instead of a human being's, reflecting the choices or natures of either "jungle gods" or their worshipers, or the specific gifts conveyed to specific members of the serpent faith. The types of serpents whose features are represented are likewise innumerable, such that it might be fair to say there is no such race as "serpentfolk" -- only human beings or those whom they worship, affected by something in the nature of the jungles' native mythology.
Further confusion arises from the encounters Herring and Theril have had with serpents and serpentfolk in Grat'ha who appear or purport to be gods themselves; as Theril put it, the behavior of some is more godlike than that of others. A group of serpents and serpentfolk who were worshiped as gods by local Grat'han tribes were observed to eat greedily, take routine and mundane interest in material things for their material uses, and lead slaves around the jungles to carry the offerings they received from their worshipers, without appearing to notice Herring and Theril as they watched and followed, though the pair were cloaked only with a simple spell apiece. Nilassashe, on the other hand, a serpent woman who traveled alone through the jungles and met with Herring and Theril personally, and whom Dotrum and two of his one-time companions worshiped as a goddess, really seemed, behaved, and reacted -- to the extent the words mean anything to an atheist like Theril -- like a divine being.
Outside the Grat'han jungles and their vicinity, Black Steel personnel have seen serpentfolk only in Night Harbor, and only in passing. Rat Pack members, notoriously unreliable in their reports unfortunately, claim to have seen serpentfolk whose human features were as pale as might be expected in those climes, naturally unlike that of serpentfolk native to Grat'ha. Their descriptions are all essentially similar anatomically however -- the pale-skinned serpentfolk seen in Night Harbor resemble merfolk so closely as to raise questions of whether they are related in some fashion, though the serpentfolks' tails are significantly longer and of course do not end in flukes. Unless the Rat Pack's members are making the whole thing up.
The sorcerous aptitude of mortal serpentfolk within Grat'ha is assumed to be the same as for any group of human beings, at least to the extent they are actually humans modified by gifts of the "jungle gods." Since the tribal conditions in Grat'ha render the transmission of sorcerous knowledge all but impossible between would-be wizards all but impossible, it will be difficult to put the matter to a test. Theril observed that Nilassashe had spells of some kind woven around her, but whether these were related to active sorcery or to the nature of her existence or to some effect of myth and faith in the sorcerous world is as yet unknown.
