Troll culture is low if at all existing in the eyes of the other races. This is, however a misconception. Trolls have a very rich and diverse tribe culture. No tribe culture is the same however. This is why many other races see them as a race without a culture. Troll culture does have some consistency to it however. Their whole race flows around ancestor worship. In Troll society, where you come from is important first and what you do second. Trolls aren't very efficient compare to other races, but everything somehow always works out for the best. Trolls are therefore generally carefree. Trolls have little love for the secrets of the world, they see what works and what doesn't work by doing it, but forget about it in a year or so and never teach these valuable lessons to their peers. "They will learn eventually.. or not, which means it isn't important." seems to be their motto.
Ancestor token
Most adult trolls carry something with them that belonged to one of their ancestors. This token must pass on to a different troll if they die, preferably with some knowledge about the ancestor and some knowledge about the troll that carried it (who will now become an ancestor!).
Diet
Trolls are Omnivorous , like most of the intelligent races of Heimr. But they do tend to eat more meat than other races, as they hardly gather, but hunt all they like. Trolls usually eat their meals raw or roasted on a simple campfire.
Language
The native language, Trallvoj is still commonly heard amongst troll tribes. There are even quite a few trolls that see this language as their primary language. The lesser known and more sophisticated counterpart of Trallvoj is called Begvoj is is often employed by the trolls of higher standing.
Art, music and literature
Warpaint, song, rituals and a large collection of art (mainly ritual masks and little idol dolls) are an essential part of Troll culture. They tell each other story's around the campfire, but most trolls only know half the story's because trolls walk in and out of the story halfway, all the time. This results in a form of "game" where the story needs to be told by several storytellers, all trying collectively to finish the story. Trolls rarely write, if at all.
