Do trolls like warm or cold?

Trolls are often depicted in folklore and fantasy as preferring cold, dark environments, such as caves or icy mountains. This association with cold is partly due to their mythical nature, which often portrays them as creatures that thrive in harsh, wintry conditions. However, interpretations can vary, and some modern portrayals might depict trolls in different settings, but the traditional view leans toward a preference for cold.
