it also wouldn't really explain the total death of the battery's charge.

You should disconnect the battery ground cable, hook it back up with an
ammeter in line (most multimeters have a current setting).  Start high,
using the one rated at 10 amps, note the current draw with everything
off.  If it is more than a 100 mA or so, start pulling fuses - see if
removing one makes the current drop a lot.  If it does, you at least
know what branch of the wiring a short or malfunctioning device is on.
