Help name the anti-Pluto's moon

The anti-Pluto�the large Kuiper Belt object named Orcus�is similar to Pluto in many ways: similar sizes; each with a single known moon; possibly similar origins; and, most strikingly, similar orbits in size, apsides (i.e., perihelion and aphelion) and [rather large] inclination. They are different in one glaring respect: Pluto and Orchus have, and will always have, exactly opposite positions in their respective orbits. As I understand it, this is due to their orbits being regulated by Neptune, with both orbs "circling" (ellipsing?) the sun twice for every three orbits of Neptune (making each a plutino).

Orcus was discovered in 2004 and its moon in 2005. The latter has only just recently come to need naming (presumably the former will also become the sixth official dwarf planet before too long). Mike Brown, of Caltech's Division of Geological and Planetary Sciences, has an extremely interesting entry in his Mike Brown's Planets blog that talks about this need to name Orcus's moon and that invites submission of names, with rationales. Be sure to read at least some of the comments, which are full of suggestions (there are 249 as of this writing). I was hoping to have a stab at it myself, but I'm far too ignorant of mythology [via today's Astronomy Picture of the Day].
