The barriers that originally sealed the secret realms in the Periphery of the Sunset Mountains had all vanished, leaving only the entrances.
Moreover, the monsters within had been swapped out.
No longer were they the terrifying Abyss Lords with chaotic auras; they'd been replaced by relatively normal Lord-level bosses.
The monsters' levels had dropped quite a bit.
Though the new lords that had appeared were still outrageously high-levelled and well beyond what human players could handle at the moment, they weren't as hopeless as those Abyss monsters who often had levels in the hundreds.
Additionally, now if someone accidentally wandered into these secret realms, as long as they didn't deliberately provoke the monsters and draw their aggro, they wouldn't be attacked and could still escape unscathed.
