Tyrafdir

The most commonly seen hydra famously has five heads that it uses in unison to attack prey or assailants. Scattered across the Inner Sea region are more fantastical breeds of the beast, each with their own curious evolution and hunting behavior.

The process of sapient species finding kinship with those who are less self-aware can be observed easily throughout the natural world. Humanoids keep dogs, kobolds care for reptiles, and so on. More terrifying, as it is on a grander scale, linnorms with a strong attachment to the First World sometimes keep mutated hydras as pets and guards. Known to Ulfens as tyrafdirs, these beasts have the unique ability to create illusory doubles from the ruined stumps of their necks. These serpentine guardians serve as strong protectors in the Land of the Linnorm Kings, where their fey-warped physiology deters many a would-be monarch from claiming their master's head. The domestication of tyrafdirs by especially powerful spellcasters to serve as guardians has been known to take place, often combined with magical traps that attack the intruder's mind.
