Oh boy, that seems interesting. The Echochamber that was previously turned off is now on. Its eyes glow a milkshake white, the same kind of colour you'd find at a 1950's diner. You always like those.
When the aboveground was still new for you, your sis allowed you to experience super humany things, including going to diners. You remember going to a diner with your friends; you think it was Meowrage and Suki, and the three of you talked for hours about random nonsense like pokemon or something like that. You don't really remember exactly what was said, but you remember it being a really good time for all three of you. You also remember that Suki rubbed it in Mew Mew's face when she couldn't come for some reason.
The Underground had its perks too, nowhere else on earth could you find crystals the size of your body and be able to use them in magic spells. Nowhere else before the barrier broke could you find a sandwich in the shape of a sword, nor could you find a steak grilled in the shape of a giant robot. Nowhere else on earth has glowing trees, or any trees whatsoever underground. Well that last part may be untrue, because some humans may have planted trees in biodomes underground.
Still, you've found things to enjoy in both the major places you've been in your life, be it under huge amounts of ground, above huge amounts of ground, or this new thing you'll be in very soon, whatever it may be.
