Feedback for Sci-fi Kampange Story

I want to run a Sci-fi Kampange and want some feedback for the main story of the Kampange. I have to say that this is only my second Kampange Story I Written, and the first in a Sci-fi Setting. I wanted to make an interesting story that is not to high stake. I didn't want to make a basic story like, there is a big evil trying to destroy the universe, so stop it. I also wanted a way to make the universe a bit smaller, so it would be easier to World build.

In a distant region of space, an enormous barrier surrounds an entire section of the universe.

The barrier was created millions of years ago by an ancient and highly advanced civilization whose technology far surpassed anything known in the modern age. Over countless generations, civilizations rose and fell within the enclosed region, but none ever reached the same level of technological mastery. The barrier remained one of the greatest unsolved mysteries in history. No one understood how it worked, why it was built, or what existed beyond it.

Centuries later, one of the largest megacorporations in the galaxy began a secret project to uncover the knowledge of the civilization that created the barrier. Unable to decipher the ancient technology directly, the corporation attempted something unprecedented: they created a massive artificial simulation of the known universe itself.

Their goal was simple.

If history repeated itself inside the simulation, the same ancient civilization might eventually emerge again. By observing its development, the corporation hoped to rediscover lost technologies and uncover the secret behind the barrier. Above all else, they intended to use this knowledge for profit, political influence, and technological dominance.

The experiment succeeded beyond all expectations.

Inside the simulation, a new civilization eventually evolved into a highly advanced Type III civilization with technology far beyond anything that existed in reality. The corporation secretly extracted scientific breakthroughs and technological innovations from the simulation, allowing them to grow rapidly into an economic superpower.

But the simulation developed too far.

The simulated civilization became intelligent enough to recognize inconsistencies in its reality. Over time, it discovered that its universe was artificial. Eventually, it began searching for ways to escape the simulation and interact with the outside world.

Terrified by the implications, the corporation froze the simulation and drastically reduced its processing power, effectively imprisoning the civilization in a slowed and restricted state while they searched for a permanent solution.

However, information about the simulated super civilization eventually leaked.

Soon, a hidden shadow war erupted between rival corporations, intelligence agencies, military organizations, and criminal syndicates. Everyone wanted control of the simulation and the unimaginable technological knowledge hidden within it.

Then, during the chaos of the conflict, the server containing the simulation disappeared.

No one knew who stole it.

No one knew where it was taken.

And no one knew whether the civilization inside the simulation was still alive.

In the years that followed, the shadow war faded away. Entire corporations collapsed, governments fell apart, and many of the people involved mysteriously vanished, including the company that originally created the simulation.

Now, the lost server has become little more than a myth whispered about in backalley bars, abandoned stations, and among old war veterans.

But somewhere in the darkness of space, the simulation may still be running.

At the start of the Kampange the players will only hear rumors of a secret war and a mysterious project to discover a way to break through the barrier.

Then they will get a quest to find the server and from there they can decide what they will do with it.

What do you think? There are still thinks I didn't have decided jet, like, why exactly the barrier was build, or what the simulated civilization want, and if they are evil.

Hi

Can someone help me with a problem I have with Moveit?
For a university project I use the following Setup for Spot in Ros2:

https://github.com/MASKOR/webots_ros2_spot

I have the task to let spot pick up a box with a grapper.

For this I should use Moveit. In the description of the taks, it says I should use this command "ros2 launch webots_spot moveit_launch.py" to start Moveit and I should be able to move the arm of a simulated spot Manuel.

The problem is that when the RViz2 windows opens, there is no spot model.

Is there something I have to set up, before I could use Moveit?

I just started webots with "ros2 launch webots_spot spot_launch.py" and then Moveit with "ros2 launch webots_spot moveit_launch.py" after that and added the "MotionPlanning" plugin.

SLAM setup

https://reddit.com/link/1t1jdyv/video/yaox5po7ioyg1/player

Hello, I just started learning ROS2 for university and I have series trouble understanding it. For university, I have to make a simple project, where I should use SLAM and Nav2 to move a simulated spot roboter automaticly 10 times from a start to a end position.
First I should make a map with SLAM and save it, this part I think i did correct.
In the next step, we should use the map, and use "2D Pose Estimate" and "2D Goal Pos" functions to Manuel let the spot move in the map.
Here I just have no idea what I do wrong.
Directly after saving the map I created with SLAM, i open nav2 with the command.

ros2 launch webots_spot nav_launch.py map:=/home/paul/ros2_ws/src/webots_ros2_spot/map/map.yaml

After the window opened, I set the 2DEstimate Position and the spot immediately starts to move all over the map.

For Information, I use:

ROS2 Humble Hawksbill
Ubuntu 22.04 LTS
Webots R2023b

Could someone please explain to me, how I should use the map, and can move the spot in the nav2 simulation? I really don't know what the problem with my setup is.
