The Supreme Being of the Hall of Valor

For example, there was a Supreme named Alva who made a move sixty years ago, accompanied by a strange swirling yellow sand, forcefully refining a fellow Supreme of the same level.

 After that, it is said that this Supreme has been in seclusion ever since, never to show himself.

Now, the event organized by the Hall of Valor in collaboration with [Transcendence] offers incredibly lavish rewards, including items that could grant direct access to divinity. Moreover, the released list of rewards is only a partial glimpse; who can guarantee that such hidden Supremes won't be tempted?

Not to mention...

"We also found records in our family's history books that there was an unnamed Supreme in the Hall of Valor who could withstand a confrontation with a deity for several seconds. According to the records from that time, this Supreme should still be alive."
