isei-bleeds:Speaker MasksSpeakers of a clan, elders, etc, when discussing delicate matters with other clans and their representatives/leaders, would wear these ‘masks’ that cover their mandibles to hide any telltale movements of them that could betray what they’re *really* feeling towards either what they are saying, or what they are hearing. Thus keeping their intent, if any, known only to themselves. There are modern designs, of course, but many chose traditional covers. Some are simple in appearance, others are ridiculously intricate. -- source link
