Getting in the ruins was no problem. Hopefully, I can say the same for when I leave. I led with Jendoa. That way, I can scout out for what type is dominant here. There were three paths, a nearer one lead leads right, and a left a right one farther down. There was a marked wall in between the staircase-paths.
It was written in Unown, and I could read it, although I needed an empty piece of paper to "memorize" it. The trick is, the writing is just the normal, everyday Latin, except with a difficult font. I read it until there was no more to read.

"Top right"

"Lower left"

To some, gibberish. To me, directions. Thus, I followed the directions by going down the specified steps in that order. I ran into some boy after the first direction. He said he'd give me seals. After the boy I ran into a battling man with Geodudes. I picked the right Pokemon to battle with. His third Pokemon was a Bronzor however. Psychic-Steel type... I wondered how I'd approach it, but then I realized that Sparx had bite, which was super effective against Bronzors.
It went fine, even if the Bronzor had ridiculously high defense.
I followed the instructions, and found nothing but a lonely rock. Peculiar... I couldn't do anything with it. Turns out, I took the lower right path. I turned around promptly. There were four items, and an inscription. I looked at the items first. Translation can always wait. A gold nugget, a rare candy, an odd incense, and a Mind plate, with text of the back. I think I'll leave the texts alone until they get interesting...
The markings said "Friendship, All lives, Touch other, Lives to create something anew and alive." Weird. I realized I had to leave, and it was actually easier than I thought. I found the boy then talked to him. He gave nothing. Liar. Now, I had to go to the tower. I sold the gold nugget, and headed out. I bought five dusk balls with the money the shopkeeper gave me for the gold nugget. I am low on pokeballs, after all. I found a cuttable tree, and let the Bidoof temporarily be on the team for this one, and it had the TM steel wing.
The tower was a grave for dead pokemon. How depressing. The climbed the tower, and a boy on the second floor mistook me for a ghost. This may be a graveyard, but it's a POKEMON graveyard. So I fought trainers, avoided badly-placed gravestones and climbed.

The dead.

Everywhere

Essentially, as I got higher, I got more battles and stuff. The graves also became more abundant.
I got the TM for return, and thought about giving it to Luna, but then I realized. Could I use copycat on Fantina's pokemon to use her ghost-type moves against her? I decided to leave it be for a bit. It's be useful, considering that the only ghost-types I can catch can only evolve once, and I won't be seeing a Dark-type until I head farther north, but then the idea just came back to me.
Pandora. COMPLETELY forgot about Pandora. I gave return to Luna. Not only will it do massive damage with her high happiness level, but it will also do TWICE the damage with the same-type-attack-bonus, or STAB. Stabbity stabbity stab stab stab!
I think I eventually reached the top. Two old men, or old woman, I dunno. They stood in front of two graves. I spoke with them, but not before a Zubat interrupted. He just killed the mood. I got a "cleanse tag", and an HM. For what? I didn't check yet. Might as well.
"Strength" I needed the gym badge to use it. I guess It's time to face against Fantina. Hopefully, Pandora doesn't need to return to the Underworld, where I assume all ghost types come from.
