A haven is more than a Kindred's home; it is a secure resting area, safe from the threat of sunlight and other vampires. A vampire's haven is a weak spot, especially during daylight hours.
A haven may take on a variety of forms, from a rented storage unit to a private estate with a labyrinth of underground vaults. Those vampires with Protean can melt into the ground during the day, making their havens in public parks or other areas without artificial shelter from the sun. Sometimes a coterie of vampires will share a haven, and vampires often create ghouls who can keep watch for danger during daylight hours.
A vampire in their own haven has a "home field advantage" that goes beyond simple familiarity with the terrain. A vampire in their own haven is better able to stay awake during the day, and more sensitive to danger. Some vampires cultivate an intimate relationship with their havens, and use special devotions to be able to monitor them. However, a known vampire haven is an easy target for one's enemies. Strix are known to harass vampires in their havens to provoke a frenzy, while hunters may arrange for a fire or other disaster to destroy a haven while the vampire rests inside.
In Vampire: The Requiem Second Edition, the prerequsite for the Haven Merit is the Safe Place Merit. Haven is rated from one to five dots, and members of a coterie can pool their dots to obtain a better haven. Losing a haven is a breaking point at Humanity 8.
