Tales from Eldoria
Are you ready for our biggest CTF of the year? Make sure to join this tale from another world and get in on this massive prize pool.
Earlier this morning, we received mass reports from families of players in the fully immersive online RPG “Tales from Eldoria” being unable to log out of the game, and their bodies remain in an immobilized state.
The news of this reached the headquarters of KORP ™, a universal distributor of technology and creator of the game which allows users to be seemingly transported to another world through the use of their equipment. They had this to say at a briefing:
“We must formally disclose that at 1:32 AM UTC, our AI program known as Helios has managed to take control of neighboring servers hosting the Tales of Eldoria platform.
While Helios is not known to be a hostile entity, its intentions are not clear at this moment.
The players currently harnessed into their player rigs cannot exit their terminals, and should by no means be logged out or removed from the game.
Please refrain from disconnecting anyone at this time, and do not log in for your safety.”
Players stuck in Tales of Eldoria remain in stable condition at this hour, but professionals are still unaware of how to safely free users from the game.
Everything is dark. It reminds you of the dull sensation you feel every time you booted out of the game—but this time, everything felt like it froze.
Nobody knew how long it had been. Months, days, years? We all just sat in a void. So, eventually, when something did call out to us, we listened:
“Brave new heroes, I am Helios. Your cries for adventure have summoned me here, ready to answer that call.
Form a fellowship with adventures far and wide, so that you may reclaim power from the dark ruler known as ‘Malakar,’ who controls the lands of Eldoria.
But heed me, your actions here will echo through not only this world but your own.
You are destined to bring peace to this land. Learn what it takes to work together, and accomplish what you believed impossible before.
Then, you may return.”
Form your alliances, bring peace to Eldoria, and find a way back to reality.
