Changing where people end up when they die

I can't seem to find the piece of code that determines where players repop after they get killed. Any help is appreciated.

Should be somewhere in mud.h (or whatever the SMAUG equiv of merc.h is), look for _morgue for the location..... at least I believe SMAUG uses a morgue by default.....

I know where to define the room vnums but I wanna make it so that if someone is over a certain level, they repop at a different place than those of a lower level and I can't find where in the code I can set this.

That would require actually defining a second morgue. I took the cheap way out of solving this problem on Stormbringer by making the morgue an isolated room once a char is inside and changing the recall point for newbies to the center of our revised academy. As for where to change where ppls recall to after a certain level, take a look at the do_recall function, its probly in act_move somewhere.
Hope that helps a bit.
