Monsters live both in the wilderness outside safe zones and in dungeons within them. They have the run of Terra Hostili. Monsters come into being as full adults from monster spawn points, with all of their abilities. Many form social groups. If a community is isolated from other monsters it will develop its own unique language rather than learning an existing one. Monstrous beasts are not intelligent, but have an affinity for other monsters and generally do not attack them. As they come from spawn points, most monsters have no concept of sexual reproduction or gender. In terms of physical appearance, there are roughly equal numbers of monsters that read as male, female and androgynous to humanoids. Few monster languages make any distinction when it comes to pronouns. On the rare occasions where monsters deal with humanoids, they are content with the pronouns 'he', 'she', 'them' or even 'it'. Monsters with a fuller appreciation of humanoid culture and who have to deal with humanoids on a regular basis develop their own gender identity. A humanoid that ignores that identity is interpreted as being disrespectful, and thus untrustworthy. Advanced monsters appear once the local population of that monster breed is high enough. Certain powerful monsters spawn as unique individuals, with collections of abilities as diverse as any humanoid adventurer. However, monsters never learn or develop new abilities throughout their lives. The strength they have when they spawn is the strength they will have until they die. Monsters cannot use enchanted weapons and armour, and can only use a limited variety of curios.
