(In Phar's study of geography and nature, he has read a lot of texts about the Northlands and listened to many of the oral legends and stories of the Northlanders known by the silver 'wild' elves -- cousins to his people. Harqualian centaurs often visit Silverleaf and Phar met several centaur traders and warriors as a child.)
Harqualian Centaurs live in the forests of the Northlands (north beyond both the Great Forest and the Greystone Mountains) and are steadfast allies of the humans known as Northlanders living in Harqual's arctic lands. For as long as those peoples have lived on Harqual there have been Harqualian centaurs living alongside them, or at least that's what both the Northlanders and the centaurs say when asked about their shared heritage.
All Harqualian centaurs have thicker hair than centaurs of other lands (and worlds) and the human torso part of their body is covered with hair front and back. Males often have thick beards, which are usually kept braided and their long manes are always tied up in a ponytail. Females do not have facial hair and their manes are left loose to blow in the frigid winds of the Northlands.
The origin of the Harqualian centaurs of the Northlands is a mystery that baffles even the high elves of Kingdom of the Silver Leaves. The traditions past down from the elders of the Harqualian centaurs states that their people are the only true native race of centaurs on Harqual. These traditions state that zebranaurs came to the Lands of Harqual during The Time of the Calling. And while Northlanders were born in the Northlands from Cronn's tears, the centaurs of Harqual have always lived in the Northlands.
The elders of the Harqualian centaur of the Northlands won't willingly cross the Great Expanse, and they attempt to forbid young centaurs from entering the desert. For when a Harqualian centaur crosses into the Great Expanse, legend says that they will disappear in a shimmer of light. Where these lost centaurs are said to go remains a mystery.
Knowledge (nature) check for Phar: 1D20+8 = [16]+8 = 24 +2 = 26 (for Sense Motive [hunch] check)
Harqualian centaurs are stout warriors will defend their homes and kin without any hesitation. Of course, since they are strong allies with the barbarians of the Northlands, almost any conflict that continues for any length of time will eventually draw in their barbarian allies as well.
Phar knows that Harqualian centaurs have the innate ability to produce a
ray of frost spell-like ability. They have darkvision and have tough skin (+2 natural AC). They have a tradition of rangers among their people.
