The majority of Tzimisce elders met Final Death when the clan joined the Sabbat but a fair number escaped their vindictive progeny. Securing their demesnes against the ravages of the Sabbat, these vampires continues to exist much as they had for centuries, albeit more warily.

Though some refer to these Tzimisce as the "Old Clan," that is a misnomer. These hoary vampires have little use for sect, clan, or other ties. They remember well the nights of old, when each vampire was a law unto itself, and any other vampire was a potential enemy. (Note that Old Clan Tzimisce do not call themselves "antitribu," as do the surviving non-Sabbat Lasombra.)

Accordingly, Old Clan Tzimisce society is structured around individual broods comprising a sire and one or more Blood Bound childer. Childer, for Old Clan Tzimisce, fill the roles of lovers, family, friends, bodyguards and servants. Tzimisce mastery over the Blood Bond allows the sire to attune the emotions of his childer to a desired pitch. Thus, a vampire lover may be Blood Bound to feel all-consuming desire for the sire, a guard may be Blood Bound for loyalty, and a mate may be "programmed" for love. The fact that these emotions are artificial and one-sided rarely bothers the sire.

Old Clan Tzimisce rarely congregate. Other Tzimisce are, if anything, even less trustworthy than other vampires. Indeed, many Old Clan Tzimisce spend more time brooding over some millennia-old, centuries-forgotten slight by one of their "peers" than they do worrying about the very real threat that the Sabbat poses. This is not to say that Old Clan Tzimisce have forgotten their traitorous progeny. On the contrary, many Old Clan Tzimisce have gone so far as to disown younger Tzimisce entirely. These Tzimisce, the Old Clan claims, are not vampires at all, but fleshly hosts for otherworldly parasites called "Souleaters." This distinction seems to be based on the possession of Vicissitude, although some ancient non-Sabbat Tzimisce have verifiably possessed Vicissitude for millennia.

Some Sabbat whisper that a few Old Clan childer have been rendered immune to the Vinculum by their elders and sent into the world with the purpose of infiltrating the Sabbat and bringing it down. The clan publicly scoffs at these rumors, but some high-ranking Sabbat have expressed private unease about such a prospect.
