Moonview Arena (Japanese: 迎月の戦場Moon-Welcoming Battlefield) is an area located in the western region of the Coronet Highlands of Hisui. It is located west of the Sacred Plaza. It is the place where the nobleElectrode, Lord of the Hollow (Japanese: 洞窟キング King of the Cave), resides. Electrode is fought here as part of Mission 11: "Scaling Perilous Heights" to calm him of his frenzy. The Summit Camp is established between the entrance of the arena and the Sacred Plaza during Mission 17: "Atop Mount Coronet". WardenMelli of the Diamond Clan tends to Electrode here.
Moonview Arena is a formed out of a crater-like section of the mountain range. Its entrance from the Sacred Plaza is a short tunnel that bores through the mountain. Stone pillars of varying degrees of disrepair are arranged in a circular fashion around the inner perimeter of the arena. A single tree stands at the edge of the arena, where Hisuian Voltorb and the noble Electrode supposedly nestle.
