Every era on Sumatra Continent was based on the Mystic Empyrean Tentacle that was active in that period. Its birth signalled the start of the era, and its death signalled the era's end.
Every era, without exception, belonged to the Mystic Empyrean Tentacle Race, except for one. That was the era of the Empyrean Boar King, which was both short and extreme in terms of development.
The Transcendent Mystic Empyrean Tentacles had predicted that the eras subsequent to the Empyrean Boar King would belong to the Mystic Empyrean Tentacles once again.
In the presence of multiple Mystic Grade existences, the era will be based upon the individual who will be the centre for everything on Sumatra. It was Brangara during the era of the Empyrean Boar King.
