They survive in the wilds, maintaining some contact with civilization, but mostly staying alone. They are not the greatest fighters among demonkind, but keeping one’s wits, withstanding blows and giving no quarter still belongs to a strong individual.
Being not easy to impress, it is a certain sign of prestige for a demon lord to attract one. Working for someone, they are most useful as hunters and spies. Plus, no one can compliment better than a Telgard, who would literally worship his master and the concept of a servant, comforting his lord and aiding in all ways possible. The work contract, however, contains a non-working clause for their mating season.
When their mating season begins, the demons put aside their worship of the individual, and start to worship the concept of family. They join in groups of three and together embark on a hunt that will ensure them progeny. While hunting, over the course of three nights they catch a man, a woman, and child. From their bones and a substance secreted after devouring them, they create together a new Telgard.
During this period, their normal demonic abilities are combined, and sharing them, they will help each other out as a family should. Combat with one will be much more harder - they even recover three times faster, and can focus their strength into one. It is suggested therefore to fight the whole ‘family’ at once, rather than pick one empowered by it.
Curiously, while in this group they cannot harm a family that keeps tightly together.
