Brendan liked the idea of re-skining Dragonborn as Sleestaks in my last post, so I'll expound on that idea a bit. I'm sure there have been write ups of Sleestaks and a playable race but this is specifically for 4e D&D or a simplified/hacked facsimile.
Sleestak PCs are identical to Dragonborn, but they look like the guys pictured above and they have no breath weapon power. Instead they have one of the following powers:
one in ten Sleestaks can, in brief flashes of insight, remember the ancient secrets of their ancestors. (Roll D10 at character generation. They have this power if a 1 is rolled.) Once per session the Player can make up a detail about any dungeon environment the characters find themselves in, details may include secret doors, passwords, codes, the location of a pylon or how to operate a pylon. The DM should let the player throw their idea out there in one short sentence, but then further details are for the DM to determine. Note that ancient Sleestak technology allows for structures that are larger on the inside than the outside and other warping of time and space, so dungeon maps need not be modified except to note the location of any new Sleestak generated details. It is of course the prerogative of the DM to declare a dungeon off limits to this power because it was not built by Sleestaks or has been otherwise untouched by their weird lizardy claws.
"Sleestaks Come in Threes"
All Sleestaks that don't have Sleestak Memories have this power. At character generation, the PC will have 2 Sleestak companions who appear to be identical to the PC, have identical equipment, but have 10s in all stats, no powers, and only 1 HP. These accompanying Sleestaks may be controlled by the Player. They will not be automatically replaced, but more may be recruited if the Player wishes and the DM allows.
These are weird and maybe overpowered compared to typical 4e powers, but I don't mind. To put this in perspective, I played Rifts and liked it.
Here is where the PCs could start out or venture to in a campaign with Sleestak PCs:
On the bluffs overlooking a huge briny lake sits the city of Sleesport (pronounced Sleaze Port). Founded by a bug-eyed and lizard skinned version of Bugsy Siegel and resembling both Vegas and Lankhmar, Sleesport is largely owned and operated by a criminal gang of Sleestaks. Anything can be had in Sleesport. Non Sleestak NPCs feel a mixture of respect, fear and loathing for the Sleestaks. Sleestak PCs may be drawn into the machinizations of their powerful brethen, however, this will almost always prove to be more of a pain in the ass than a benefit for the PCs. It is rumored that a lost city lies hidden beneath Sleesport.
