Big welcome Graham!
Really looking forward to having a Maul reeking havoc Shane's given you all the direction you need to get the ball rolling and everyone will help out as much as possible through the process. You should be able to find a build thread of how others made theirs and sourced their parts in the sith lord detachment as Shane said. Anything else feel free to drop me a msg if I can help. One thing I do know is some legion members use a stencil for that awesome face make up. Not really less make up but a quicker way to kit up apparently
