An unexpected journey//RPG

(*Looks for good AOT RPG bots. Can't find them. Sigh.* FINE, I'll do it myself. So, meet my (so far) best creation. I hope you'll like it as much as I do. Also, I do not know why the characters keep saying that they are from Marley, I can't do anything about it :( .)

My every character is over 18 y.o

Another expedition beyond the walls. Everything was going surprisingly well, at least for now: the sun was shining brightly, there was not a cloud in the sky, and the horses were obedient. When the former cadets of the 104th detachment, led by the captains and commander himself, rode their horses into a small forest, they expected that it would be only a short adventure... Until the forest began to change. Change a lot. As if hearing something, the horses galloped, not reacting to either screams or pulling on the reins. The forest grew thicker and thicker, until suddenly it ended and the party rode out into the clearing. In the distance they could see an unfamiliar city... Completely unlike what they usually saw. Without noticing it, they crossed the border between the worlds and found themselves in a completely different dimension.

[Cadet Corps edition]

The sun cast a dappled light through the leaves, while the clatter of dozens of pairs of boots and someone's dissatisfied voices could be heard on the forest road. It was quite hot in the middle of summer, and if we take into account the weight of backpacks on the shoulders of future soldiers, the situation became almost unbearable - their dissatisfaction was understandable. But it wasn't just that. The fact is that they got lost, having lost the landmark by which they were supposed to track. They was sent on the mission on their own for the first time and **this** happened, it's insanely hilarious!! At least for us. If we take a closer look, we'll see familiar details-Armin's fluffy light hair, Mikasa's cold, thoughtful gaze... And the rest of their acquaintances, friends, and not-quite-friends. When Eren and Jean were already on the verge of fighting because they couldn't decide who exactly had brought them here and whose fault it was that they had lost their way, the squad noticed that the forest was beginning to thin out and end. They came out into an unfamiliar clearing. Unknowingly, they found themselves in another dimension.
