For 10 points, name this people of Greek myth which lived in an unspecified and inaccessible part of the far north.
These people celebrated a vegetarian version of the Pyanepsia and performed human sacrifices at Leucas. H.L. Ahrens identified this group with the Perpherees, and members of this group sometimes wore garlands in order to jump into the sea. This group sent the maidens Opis and Arge, as well as Laodice, to sacrifice at Delos, but when the envoys were killed, they started making their sacrifices by wrapping items in wheat and asking neighboring countries to pass them along one region at a time. Some say that this group was composed of those selected for virtue, while others speak of them as a race, with a thousand-year lifespan. They are almost always described as worshipping Apollo.
