A vigil is when a cat chooses to stay awake for the night, this being required by a ceremony or tradition (as opposed to staying awake for guard duty).
Newly appointed warriors are required to stay awake for the entire night after they received their warrior name, as decreed by the Warrior Code. They guard the camp in silence, while the other Clan members have a good rest.
In some cases, this rule cannot be adhered to, and the warrior receives another task.
Vigil for the DeadEdit
If a Clan cat dies, his/her body is taken to the center of the camp, and several of their Clanmates, usually the cat's family members and close friends, sit vigil for them through the night, sharing tongues for the last time before the elders bury the cat in the morning
