Ittul (sometimes called "tools" in Bastardised Nahumic) have their roots in the ancient beliefs of the Kamaian people, having been brought to Antediluvia and the West in general by the religions of Priya Rukmeni and Gammar Gammura. They are traditionally understood to be a third gender, and ittul can be born biologically male, female, or intersex. The traditionally defining feature of ittul is that they do not conform to gender and sexual norms: they may dress and act as male, female, androgynous, or any combination thereof, regardless of biological sex; and they may be attracted to any gender(s). More recently, different subsections within the ittul identity have emerged (the most common of which are homosexual and transgender); though while these are widely known to exist, they are still not fully understood by most of the population.
In popular belief, ittul are often considered to engage in practices and habits that traditionally correspond to the gender opposite to that they were assigned at birth, but many engage in both traditionally male and female activities and forms of expression, while others may present as the gender they were assigned at birth but take lovers of their own sex. All of these -- among others -- are traditionally defined as ittul.
In addition, ittul are often associated with being particularly gifted in a trade or -- especially in previous centuries -- in magic (though due to the stigma associated in Antediluvia with magic, the ittul community in general has tended to distance itself from it since the Technological Revolution). Communities that are still fairly religious (especially those in which the majority religion is Gammar Gammura) tend to recognise that the ittul have spiritual powers; as while most living beings are said to be made up of one "shard" each, an ittul is said to have two, giving them their unique gender/sexual roles and alleged connection to Uriyah. Many culture and folk heroes are also held to be ittul. However, ittul are not traditionally considered fit to serve as members of the clergy, though in recent decades some ittul have joined the clergy, and today there is practically no resistance to ittul as clergy except in fringe groups.
Despite -- or perhaps because of -- these beliefs, there is some prejudice against ittul among some people. Nobles, in particular, tend to discourage their children from being ittul, if only so that their children marry and produce an heir (though this is by no means a hard-and-fast rule). Additionally, people who are not of the Gammar Gammura religion may view it as unnatural. Sometimes, ittul are marginalised in their communities. Ittul are sometimes held to be vengeful if they perceive that they have been slighted, and more religious people may fear incurring divine wrath for insulting an ittul; exploiting this belief, some ittul make money through extortion, by saying that they will bless someone for money. This practice has seen a recent decline, however. Many ittul are also involved in the entertainment industry as singers and dancers.
