Host

A host, also known as a curse host or a curse user, is someone who possesses one or more curses, usually one. Hosts do not have any control over their curses, but may mentally communicate with and send information to their respective curses. A host can tell a curse what to do, but there is no guarantee the curse will obey. Generally, curses choose hosts with similar ideologies, but a certain amount of disagreement remains between the host and the curse.

Individual Host
An individual host is a host that retains some degree of individuality from their curse, such that they don't agree with their curse on everything, and maintain an identity separate from their curse. All curse hosts start like this, but the longer one remains a host, the more likely one is to lose one's identity to the curse. One notable exception to this trend is Zelodor, who remained an individual host for all his life despite being a host for many centuries.

Fallen Curse Host
A fallen curse host is a host that has lost their individuality and identity. In other words, they have been consumed by their curse, such that their ideology is indistinguishable from their curse's. Listening to a curse for several years is comparable to brainwashing; it's difficult to disagree after hearing the same ideas constantly. Most hosts become fallen curse hosts unless they die beforehand or get rid of their curses.

Multi-Curse Host
A multi-curse host is a host with two or more curses. All multi-curse hosts are also considered fallen curse hosts. Becoming a multi-curse host is extremely difficult and requires a careful amount of compromise and diplomacy. Two or more curses must be given a reason to side with each other. For example, Mandant convinced all the curses to side with him in order to establish the dominance of curses over humans, something no curse could disagree with.
