There's a valley to the southeast, the Valley of Bones, haunted by centaur ghosts. Sounds scary, doesn't it? Well think how scary it is to the centaur! Here, take this crate of ghost magnets. If you place one between the two big skeletons in the valley, the Dead Goliaths, then ghosts will wander to it. Distance yourself, take out the ghosts and get their ghost-o-plasm. I have a sneaking suspicion the Magram are VERY interested in this gunk. I plan to sell it to 'em.
