'Aidos' Underground Crystal Cove.'
The duo was indeed in an underground garden with bright crystals lighting up the cove, simulating the light of the sun and making it so the plant life of the garden can grow.
Or rather, it was really the sun's rays that were being projected here via magic, spatial refraction, and a few other things Evan did not understand.
And like its name, the owner of this garden, was 'Aidos' itself.
On a side note, it was impossible to discover the entrance to this garden if you did not possess the 'Loved By Nature' title, so those people tailing Evan and Eliza would be unable to find this even if they tried from now till yesterday.
"This is a lot to take in."
"I would tell you to take as much time as you want but we've got other places to go."
Evan spoke as he pulled Eliza up from the ground and informed her that their next destination was even deeper underground, and they had to swim through the lake nearby to get to it.
