Session 3 Walter's Great Design

The Party arrives in this large coloseum like room with bodies dangling from meathooks attached to the ceiling. In the middle of the room there's a large pool of coagulated blood and above it hangs a large cage filled with missing children. However before the party gets a chance to react Walter makes himself know, appearing on the balcony of one of the highest floors.
Walter explains his great scheme. The arena is divided into multiple rings. Every rind is separated by a force field of magic and can be unlocked by solving a riddle. In every ring they will also have to battle various of Walter's "creations" for the entertainment of the skaven spectators within the coloseum. If the party loses they have to give up Orn and the necromancer grimoire they took from Elsa. If they win they may leave with their lives and all the children. It has also become very aparant to Orn and his keen dwarven eyes that Walter is very excited about getting a new dwarf for his collection.
Without warning the first wave of creations is triggered. 2 gargoyles which the party manage to defeat with some easy. It is clear something is off with these gargoyles though as they are both filled with radioactive green fluid. Then an additional Bone Naga appears and Walter laughs like a maniac, convinced they were not going to survive. But they beat everyone's expectations and behead the beast to Walter's frustration. But he is not done playing yet!
As they make it to the force field they have to solve a riddle that came with the omnious black potion with a note urging someone to drink. By solving the riddle the party found out who should drink the mysterious potion. It was Orn. He hesitates a little but then drinks it and passes, providing access to the others and allowing them to skip a wave of attacks. The next riddle provides them with a chest from which an ominous voice asks to be 'released' she identifies herself as Nexari and offers a deal to the party. If they release her she shall help defeat Walter but she wants something in return. The party declines and locks her chest once more after getting some bad vibes.

Long story short. Our amazing herous eventually solve all of Walter's Riddles and defeat his creations. Even his most prized ones. A child augmented with green glowing crystals which the party discovers are called 'warpstone', something that seems to be very well loved with the Skavens.
After his defeat Walter is pretty infuriated and decided to play dirty. He gives the party a final riddle which he knows they won't be able to solve. However this was intercepted by a skaven who yelled the answer before he could finish. The skaven was thrown into the arena as punishment. Orn and the others caught him and saved him from dying on impact. He identified himself as Tweakers and in return for saving his life he handed them the key to free the kids. Oliver is among them but he is greatly saddened as Walter's 'greatest creation' used to be his best friend.. but the party was forced to kill him. Either way the party's success pissed Walter off even more. However he knew the game was over and so he initiated the self destruct sequence he had installed in the keep.

Knowing they had to get out and not wanting to leave Tweajers, they took the Skaven along. They escape the arena together with the children and in doing so come across a hallway full of cages. However, they were all empty. They see a human rogue looking type of girl freeing one of the last kids before taking off with them. She gives them a friendly wave. It seems they weren't the only ones thinking about freeing the children. However before they can approach she disappears.
They press on and come across a security room with security camera footage. Something which is very alien to the whole party. They figure it must be some kind of strange magic but they're unable to investigate as time is ticking. Right outside of that room though there is a noble asking for an escort.
However the children are scared shitless of this man so Plum glues him to the floor as retribution because whatever this man did to scare these kids most definitely isn't good. They continue to run and look for a way out until they find Walter's laboratory, there they meet his butler who tells them everything they would like to know about Walter and his experiments. He is also fully prepared to die in the explosion as is customary for all non PD personel to sacrifice themselves. He leads them to the door that contains the portal-room Walter uses to enter various realms.

The party is ready to step into the portal room and go. However upon seeing that the children have a good relationship with this man and don't want to leave him behind because he took care of them, they take him with and find out his name is Franklin. He is also wearing similar goggles to Walter and thuse the party decides to take those as well.
Franklin enters the portal room with them and leads them to the safest one. He starts it up and helps everyone get through it right in time.
As they appear on the other side they are met with an incredibly blinding white light...
This concludes our adventure for now.
