Something I've been hoping for awhile. Ah, time to put in a few extra options of housing.
Klamanth and Den-
Both have a unique environment, Klamanth having an underground system which seems like everyone has forgotten about.
Klamanth: Underground sewer Bolt-hole
This is a small storage room thats been cleared of debris and made... habitable, to an extent. You acquire it by speaking to that nasty bartender in the Gecko bar (name escapes me right now), because he's a known shady dealer and would probably know of hiding spots and hidden routes of the undercity sewers. A small fee, and you have a nice little hovel to put stuff.
Payment: Could be in caps, or possibly even golden gecko pelts seeing as how thats the lifeblood of the area and possibly something early nubs could farm and save up for. It should be relatively cheap, as this will be little better than a tent. However, having a stash to put stuff here while having your tent(or main home) in a more important location. This is intended for nubs as well as everyone else, serving a purpose in PVP to put ill-gotten loot.
Disadvantage: Newbs will not have to worry about this much, because of their state they shouldnt have too much of value stashed but the basics. However, for PKs and others who fill their bolt-hole with too much loot may find their stash being sold out by that Bartender. Once the value within the Bolt-hole gets so high, and beyond, the chance rises that at random intervals, the Bartender will try to call over Players, and essentially sell the location of a, "Juicy treasure of someones hidden goods! For some caps, I'll show you how to find their stash below the city..." This might be triggered instantly, perhaps, if the value within the Bolt-hole jumps drastically (like someone just got a CA and is seeking to store it) and if unlucky, he sells the location within days. Another disadvantage is that vermin may infest the stash, causing some random loot to be destroyed in the process. Another thing nubs wont have to worry much about, but large stashes would.
How to get in and out: After purchase, there should be several methods of entering that befits its unique location. 1) You should be able to use a certain sewer path beneath the Trappertown to go directly to it. (Anyone remember that useless terminal down there? It has a use now! With a special sequence code given from the Bartender, it basically is what lets you get to your Bolt-hole. Fluffer: The sequence changes old sewer floodgates and alters some paths, thus letting individuals get to their personal Bolt-holes while remaining separate from everyone elses.) Maybe pk in town chases you, you can simply escape to the sewers. HOWEVER, if he has high enough Science (like +150%) he can trace remains of part of your Sequence code. If he stalks and does it enough times to the same person, he may piece together the number which lets him follow his prey all the way home...
Now continuing, you should be able to return to the main sewers everyone is familiar with down there from your Bolt-hole. 2) You should be able to get to the Bolt-hole from the World Map directly. Possibly requiring a tool on your person, like a Crowbar to sneak from outside town to the Bolt-hole. This could be a method of PVP as well, giving people who went through the trouble of acquiring the Bolt-hole and keeping it hidden, letting ambushers swarm from the sewers upon their enemies. Epic sewer fight below the city, anyone?
Physical Details!:The Bolt-hole could be the bottom of a ladder alcove, that used to lead up to the outside world, though which is long since covered with desert or ruins. It could be a small equipment storage closet, with the hulking remains of some kind of pump occupying half the space of the room. Overall it should be cluttered, dirty, and with little room to move around in, with a little crate for storing stuff as well as the floor. When exiting, one uses a wall terminal just outside the room/alcove in the main sewer tunnel, letting you choose where to exit: Main sewer or straight to World Map. Going straight to World Map might require a Outdoors or other Skill check, possibly with random encounters depending on the result. Maybe failures tossing you back to the Main sewer due to you becoming lost and having to return there as it was the only sure location you knew of.
Ok, I wrote alot more than I wanted. I have more for another cave location(With its own little quirks) for a single person to hide, as well as others for the remaining cities. I am confident I could conceivably come up with one special 'home' per city because of the unique environments and city parameters each represents. Please give feedback.
