*Source: Monster Manual (2024) p. 329*
Adult white dragons claim large territories and are often the mightiest predators in those lands. While some lurk in their lairs for months, others regularly soar over their domains. When they spot something moving on the ice, they might swoop down to feed or extort food and offerings from sapient creatures.
## White Dragons
*Dragons of Cold and Cruelty*
- **Habitat.** Arctic
- **Treasure.** Arcana
Among the most primal chromatic dragons, white dragons prioritize survival over all. Life is harsh and uncertain in the arctic expanses, glacial heights, and frozen seas where these dragons dwell. White dragons fiercely protect their territories, scouring the frigid regions for food and evidence of trespassers. Most white dragons ignore the plots of smaller creatures and other dragons, concerning themselves only with their own survival.
White dragons create lairs to defend themselves from other deadly arctic creatures and from dangerous natural conditions. Within these shelters, white dragons hoard testaments to their superiority, such as monstrous skulls, the gear of defeated rivals, and curiosities that capture their interest. To protect such treasure, white dragons coax ice to form over their hoards or sink their wealth in frigid pools. For white dragons, each piece of treasure embodies a victory—the details of which inflate as these dragons age.
### White Dragon Lairs
White dragons brood in bitterly cold lairs clawed from stone and ice.
