Plump, incandescent pillow
The plump, incandescent pillow was an artefact offered for 5 mayan crowns in the Shop of Wonders in Delos. At first glance, this pillow seemed to be made of nothing. However, closer examination showed that it was actually fashioned out of extremely thin and light threads. A thin, lulling vapour floated around and through the pillow, and as it moved, it cast off flickers of light which caused the pillow to glow slightly. This artefact, when dropped in its owners artefact bed, expanded the bed's capacity to a maximum of three people, instead of the standard two.
