A malak (聖隷 seirei?, "holy servant") is a being part of the malakhim race in Tales of Berseria. The malakhim are a tribe of spiritual beings who use the powers of nature and are used as familiars. The future of the malakhim form is that of the seraphim seen in Tales of Zestiria. An Empyrean is an extremely powerful malak. Malakhim are beings whose origin can be traced back tens of thousands of years.
Malakhim are spiritual beings who have always existed, invisible to the human eye due to their poor spiritual powers. The ritual performed three years prior to the beginning of the story, known as the Advent, resulted in humans gaining the power to see malakhim. After that event, malakhim were somehow enslaved and used by exorcists to enact magical effects. They can exist in both human and non-human form. Likewise, they are regarded by exorcists to be without ego, mere tools, but the existence of Eizen and Bienfu, with their own strong personalities, act as counters to those assumptions.
According to Eizen, a malak's true name holds a special meaning toward themselves and is not something to be told lightly to others, except to the their vessels. When it is told to those other than vessels, true names can mean both "an unbreakable trust" and a "love confession". After Laphicet assumes dragon form and takes on the name "Maotelus", humans lose the ability to see malakhim, who, over time, become legend and are known under a different name, possibly coined by humans.
- The word Malak is Semitic for "angel", originating in Arabic before spreading to other languages.
