The group I GM for has started to obtain a good deal of wealth, and in the process are learning about the 40k world. The party's rogue trader happened to stumble upon a short writeup online about titans, and immedietely wanted one. Now I figured it wasn't particularly likely, as after appropriate mods, they had to roll less than a 05. But of course, one natural 01 later, the party is now searching for their titan.
I explained that there was a forgeworld with an ancient, decrepit titan legion that was recently attacked from orbit and ended up with a heavily damaged Warhound. The legion doesn't have the means of repairing their damaged titan in their current state and are requesting the titan be taken to another legion or forgeworld for repairs. A rogue trader ship that is able to provide this service will be able to call upon the legion for support in the form of the repaired titan, though the legion retains the right to refuse missions requests they feel are too trivial or suicidal.
I'm wondering if this is too big of a prize for the party, as they're barely rank 3 at the moment. And if it is, what kind of complications could I use surrounding the forge and the titan without simply taking the titan away from the party?
