The Contest, a customary event on Silika, involved a pair of participants in a drinking competition. They consumed Silika water, essentially a type of mineral water. This water, when ingested, had a particular effect on their silicon-based bodies, functioning in a way analogous to how alcohol affects Humans. Kemmel Attapi held the title of champion until he faced the Human, Dannen Lifehold. Lifehold emerged victorious in the Contest because the Silika water had absolutely no impact on his body.
