Locations on Atlantis
1
A House from Cycles Past (Riddle)
Region: Oikos of Atlantis
Like some sort of forgotten creature, an abandoned house hides underneath a bridge. And hidden it will remain, as the trees and plants have enveloped it in the most natural of disguises.

3Across the Board (Riddle)
It's in the Horus Repository. You need Knowledge Sequence 2 to enter.
Region: Porimos Ring
Life couldn't get any better than this. I get to watch magnificent beasts gallop around the track from the best seats in Atlantis. There's nowhere I'd rather be than sitting here under the stars with my best friend.

5And My Pickaxe (Riddle)
Region: Porimos Ring
“Break that boulder... Carry those rocks... Faster now!" I've absolutely had it with people telling me what to do. I'm going to start my own quarry on the other side of the palace. At least there I can dig for adamant in peace, and at my own pace.

7The Son Who Faced the Sun (Riddle)
Region: Royal Mountain of Poseidon
I am standing tall with my ten brothers. We surround our mighty father, Poseidon. Silent. Watchful. With a waterfall at my back, I have the most glorious view of Helios retiring his flaming chariot for the night.

9Tossed for Tyche (Riddle)
It's inside the Archive of Hebe.
Region: Porimos Ring
Like so many coins, I was tossed into a fountain for good fortune. Finding me will be fun. It's not every day you get to dance with the dolphins of Atlantis.
