Once begun, these gathers usually involve the rites demonstrating status to decide on leadership for the meeting. The rites can take days to accomplish, and must be redone for every Gather, as no two will have the same Gangrel meeting under the same circumstances. Once the hierarchy for the Gather is established, the business at hand can be dealt with. However, a Thing rarely lasts more than a week.
Grand Gathers are known as 'Allthing', and must be summoned only by the most respected (or feared) Gangrel among the clan. In a similar way, a Revel is a Gather organized to make war against a common enemy.
