Greetings, brethern,
I am toying with the idea of starting a little series of games involving the "Beast House" [DotdG]
My basic idea so far:
One of the creatures the BeastHouse uses in an illegal arena escapes into the hive. The creature winds up in a downtrodden section housing a REALLY LARGE waste refinery. Think about lots of pipes and canals from diverse waste systems from other parts of the hive ending up here. While smelly and disease ridden, still some poor people try to make a living here, since the guild running the waste refinery (and an "attached" food ration manufactorum..you catch the drift) often need some unskilled extra hands to do the work. So, a small desperate slum has grown home to some thousand people.
Here, the creature lurks and starts to kill. First, no-one cares. But later, rumours spread about the strange killings (no corpses found, but spots of blood). The acoltythes are sent in to investigate. The =I= expects some kind of new "death cult", but is prepared for everything.
My idea for this first game is for the pc to investigate the murder sights and find clues that point towards the lair and/or mode of attack. Afterwards, they shall confront the creature and kill it...to find a small, malefunctioned device implanted to its neck/head (the drug device for combat/poisen infusion...well, poison failed!).
My first idea for the creature was a big spider-like xenos dropping from a spider-thread from above, snatching its victim and snaping back into the darkness between the pipes and the ceiling (like a bungjee-attack). Self-pregnating and already having hatched four to six "youth" which where hunting independt. While I liked the concept for the "attack", such a creature wasn´t making any sense as an "arena combat beast". So, I discarded it.
What I need now is an idea for a xenos creature that would be a likely feature in an arena but stealthy and smart enough to "hide" in a hive slum settlement . The only "no go" is a creature actually lurking in "the sewers". This is much to obivous and I would really like to use the sewers as a "red harring" in this adventure.
Any suggestions? THANK YOU!

Actually, the name was created by a fumbled spelling of the word "Raubtier" (Predator), which lead me to use the name "Raubtyr". Just like some other terms are just a "re-spelling". Ttake the japanese "ruksaku" for what we call "Rucksack" (backpack) or the engl. "Abseiling" for descending a rope in a certain way.
