Vampires, canonically, do not sleep as mortals do, as they are dead. However, they still require a period of rest, known as a Slumber, to allow their bodies time to regenerate and, some say, to allow their vitae to feed their Antediluvians.

Several things are adjusted to help facilitate scenes and generally improve quality of life for vampire players.

1: You are required to slumber each day, but sleep does not start the moment the sun rises. When the sun comes up, you must start making stamina checks to resist the effects of slumber. One per hour, starting at diff 3 and going up 1 per hour until you fail. Failure means you must stop what you're doing immediately, and find a place to sleep. It does not mean you fall down immediately, only that you must immediately start searching for a place to lie down and enter slumber. No vampire above elder can resist the noon day sun however. At noon, if you are still awake somehow, you fall over into slumber. You have been warned.

2: Slumber, in Shadows of the South, only lasts for a period of time equal to the ‘normal’ amount of sleep required for any mortal. This means a 8 hour period, taken at any time throughout the day. Now, what does this mean if you are a Vampire who chooses to be awake during daylight hours? Well, the sunlight will still burn you, but so long as you remain indoors with the curtains drawn, that will pose no issue to you, nor will it impose the normal penalties to you that it might normally in a Vampire-only game (i.e. no reductions to your die pools).

3: You lose one blood point when you rise from sleep. This cannot be avoided.

Torpor is s the deathlike sleep common to the undead, particularly among ancient vampires. Torpor may be entered voluntarily (certain undead, weary of the current age, enter torpor in hopes of reawakening in a more hospitable time) or involuntarily (through wounds or loss of blood). Once in torpor, a character remains dormant for a period of time depending on her Humanity or Path rating.
Humanity/Path Length of Torpor
10 One day
9 Three days
8 One week
7 Two weeks
6 One month
5 One year
4 One decade
3 Five decades
2 One century
1 Five centuries
0 Millennium+

Following this period of rest, the player may spend a blood point and make an Awakening roll for her character to rise. If the vampire has no blood in her body, she may not rise until she is fed; if the player fails the Awakening roll, she may spend another blood point and make an Awakening roll the following night. If the vampire rises successfully, she is considered Crippled and should either spend blood or hunt immediately.
