Helios Bay

Helios Bay, what seemingly seems to be a small, insignificant group of small volcanic islands, is home to the Solar Rune, according to the temple in the Bondu Realm. The lava here has also been reported to intentionally move towards living beings to engulf them in flames, and those who fall in the lava later swim out as walking ashes. This myth is somewhat popular, but you're the one that knows it's true, and it's due to the Solar Rune. The Solar Rune must be hiding in the lava, enchanting it and giving it weird properties. You'll have to FIGHT your way to the rune.
