You read the inscriptions and learn that three sages once debated the riddle of swords.

There are words on it ... lemme try to read them...

Oh, when they were building this secret vault, three sages came here to debate the riddle of swords. They also left inscriptions to record the discussion for posterity.

We really came to the right place. The ruins are indeed related to "swords".

Endmin, let's keep going. I wanna see the wisdom of these ancient sages.
