High up on the Tikranor Plateau of Rakore...
Two Will-o'-Wisps have 'acquired' a behir, and the two species have developed a strong symbiosis. The Will-o'-Wisps occasionally lure their behir, whom they have named Ish'tir, to new victims, while Ish'tir provides excellent protection for the Will-o'-Wisps. Ish'tir is also immune to the Will-o'-Wisps' electrical charges, and allows that the 'blinking lights' can lead him to food. Ishtir ate the third of the Will-o'-Wisps, when it tried to cow him and wouldn't shut up; since then, the two remaining Will-o'-Wisps have developed a healthy respect for their behir, and leave it be when it's irritable.
The three of them have carved out a niche for themselves near the lake that is the headwaters for the Tikranor Flow. The terrain is rough and jagged, but supports bountiful herds of goats, sheep, mountain antelopes, wild donkeys, and even small herds of long-horn cattle. Most of the predators are big cats, bear -- and behir. Ishtir destroyed a small human community to make his lair, and ranges as far as 30 miles out. His lair has accumulated various 'shinies' and other objects of his affection, and the Will-o'-Wisps have led him to caravans, adventurers, dwarven nomads, and even undead with bits of flesh still on them during leaner times. The Will-o'-Wisps also serve as an early-warning system against roc-hawkes, allowing Ish'tir to become big and powerful, even for a behir.

The behir's lair contains considerable treasure, including the remains of a small clan of dwarves. The only things the behir did not destroy were silvery, shiny things such as platinum, silver pieces, and highly bossed armor. Everything else was eaten -- but what could not be digested, was regurgitated and scattered about his lair.
