arcpy - Python Script to convert a mass of KMLs to a single fGDB

I have a mass of KML files, approx 350+ that I need in a single fGDB. I lifted a string of code from ESRI help to attempt to do this - I got it working to the point of creating all the individual gGDBs (one per KML) but its failing with an invalid character in a variable somewhere. Below is the code, and then the error that it throws out. I've added some print commands to show whats in the variables right before it fails. Help? Also, this is my first time trying to use python for actual work, so I apologize in advance for n00bish mistakes.

# Name: BatchKML_to_GDB.py
# Description: Converts a directory of KMLs and copies the output into a single fGDB.

#              A 2 step process: first convert the KML files, and then copy the featureclases

# Import system models
import arcpy, os

# Set workspace (where all the KMLs are)
 arcpy.env.workspace="C:\\Users\\mperez\\Desktop\\IT-Paths"

# Set local variables and location for the consolidated file geodatabase
outLocation = "V:\\2155\\active\\215510456\\GDB"

MasterGDB = r'AllKMLLayers.gdb'
MasterGDBLocation = os.path.join(outLocation, MasterGDB)

# Create the master FileGeodatabase
 arcpy.CreateFileGDB_management(outLocation, MasterGDB)

# Convert all KMZ and KML files found in the current workspace
 for kmz in arcpy.ListFiles('*.KM*'):
  print "CONVERTING: " + os.path.join(arcpy.env.workspace,kmz)
  arcpy.KMLToLayer_conversion(kmz, outLocation)



# Change the workspace to fGDB location
arcpy.env.workspace = outLocation

# Loop through all the FileGeodatabases within the workspace
wks = arcpy.ListWorkspaces('*', 'FileGDB')
# Skip the Master GDB
wks.remove(MasterGDBLocation)


for fgdb in wks:  

  # Change the workspace to the current FileGeodatabase
  arcpy.env.workspace = fgdb    

  # For every Featureclass inside, copy it to the Master and use the name from the original fGDB
  featureClasses = arcpy.ListFeatureClasses('*', '', 'Placemarks')
  for fc in featureClasses:
    print r"COPYING: " + fc + r" FROM: " + fgdb 
    fcCopy = fgdb + os.sep + 'Placemarks' + os.sep + fc

    print r"fcCopy = " + fcCopy
    print r"MasterGDBLocation = " + MasterGDBLocation
    print r"fgdb = " + fgdb
    arcpy.FeatureClassToFeatureClass_conversion(fcCopy, MasterGDBLocation, fgdb[fgdb.rfind(os.sep)+1:-4])


# Clean up
del kmz, wks, fc, featureClasses, fgdb

Output from shell showing error:
