Background
The Theese family is an ancient family from Phlan, probably present at its founding over a thousand years ago. The Theese family possessed some minor nobility, allying itself with Valjevo, but they had a secret: they were demon worshipers.
The Theese family grew powerful from these links, but it came a cost. This cost was usually bared by some innocent, but during the second destruction of Phlan by the fiend Tyranthraxus, it was borne on the Theese family itself. By this time, they had been neglecting their duties, and their benefactors believed a they sought treasonous joining with the draconic-like fiend. Thus, the Theese family was cursed, stripped of their power and place, and hounded by evil.
Such was the history of Vardrin's family. He thought he had escaped it; he grew up reasonably safe with is mother elsewhere in the Moonsea and was ready to start a new life. But then the fiends came, slaughtered his family and the other villagers. Cruelly, they left Vardrin alive, the lone witness to the destruction.
After the "incident", Vardrin burned with a new purpose---to destroy the fiends who ruined his family and to avenge similar "crimes" elsewhere. He studied their ways, and bound lesser creatures in order to created the pact which awoke his otherness. Some say the otherness was always there, dormant from the time of the benefactors. Regardless of the source, Vardrin has been wandering Faerun trying to avenge is family's faults and seeking the weakness of their mysterious benefactors.
Personality
Vardrin has a very intense personality---it is prone to acting impulsively and quickly, as if time was precious. He speaks forcefully and passionately, and his voice is strangely enthralling. However, he has a secretive side as well as indicated by the way his hides his abilities under simple and sometime glamered clothes. The otherness of his past is something his avoids discussing, though he will discuss the proclivities of fiends and the best way to combat abominations from the outer planes with a fervor and knowledgeable mind.
Vardrin sees his path as using the tools of evil against evil. Thus, he is interested in obscure lore, especially outer planar lore. He will take up the banner for causes against tyranny and evil, especially if magical or planar interference is suspected. He is a stalwart friend and implacable foe.
Appearance
At first glance, Vardirn appears to be an unarmed, common traveler with a well worn dark cloak, pale linen shirt with a somewhat worn black vest, dark breeches, and sturdy boots. At second glance, the power which touches Vardrin is apparent in his pale skin which contrasts his ample red hair and goatee, the strange whiteness of his eyes, and the intensity of his gaze. It is when he speaks that the otherness about him is most clear: it is a clear timbre that somehow resonates in your mind.

As for Vardrin's role in the party, I see several. Vardin would fill the needed "face" role, as he has high charisma and high socials from his warlock invocations. Secondly, Vardrin provides secondary support in several roles: Give him a scroll/wand, and he can use it due to a warlock's master of use magic device (backup healer? He already has a wand of cure light; backup buffer? Give him the scrolls, etc.). He can coordinate with Broddy for arcane artillery as well. Finally, with his detection and movement capabilities (he sees invisible and in darkness and can spiderclimb), he provides unique capabilities to the party.
