The Angels cursed Cain that we all know, but God gave one last chance to Cain through the path of redemption, in the light of The Golconda.
Golconda is a state that a kindred can achieve in which he is in Peace with his beastial nature and can control The Beast, a Vampire is no longer held by the shackles of undeath but he returns to the mortal world, of course the Path to achieve Golconda is never easy, much of how it can be attained has been lost, and the Camarilla rarely speak of it, the Sabbat Shun it entirely. But the state of Golconda can be compared to achieving the Nirvana.
Searching for Golconda is by no means an easy task, it is dangerous indeed, for a kindred must repent for all of his sins, and then a test of the mind must be accomplished, not much is known of this "Test" but if a Cainite fails this test then he is forever lost to the Beast he falls into Wassail.
Wassail: Norse,"Be in Good health" Also: Drink, Revel, Party
The Wassail is the last frenzy a vampire experiences, after that Colossal Frenzy there is no turning back, the Beast takes over for good and a vampire ceases to exist, his mind is destroyed and all that remains is unchained aggressiveness and destruction, a Berserker state that never ends until, like a rabid dog he is put down. A Vampire in this state is known as a Whight.
