Someone with the Jumper (world-jumper) advantage can escort other people with the Jumper (world-jumper) advanatge, according to b. 64. You can also take warp and the warp jump enhancement, to be able to teleport on the world you are visiting. Would this allow you to bring along other people on your warps when you are Warp Jumping? Would you be able to bring Jumpers along on Warps that remain on the same world?
