They're all via PINmail, and appear very early in the morning. There's a bit of bark with a clawed symbol carved into it with each; they look something like three overlapping fishhooks with a dot in the crook of the first.
Chris gets a small pair of field vision goggles made of indeterminate metal covered in a strange alloy. Their shape is a bit odd, but they fit a human face and see in the infrared spectrum.
Eiko gets a bit of alien computer from a derelict shipwreck the yautja found a few years ago.
Claire gets a small empty box of wood with a bone inlay on the top. The design is a spikey symbol.
Derek gets a wierd viney thing in a carved wooden pot. The pods are probably going to track his fingers in a disturbing way.
Alice gets spiked metal throwing stars, because in some ways predators have no sense at all. There's only three, and they don't have the interesting qualities of the disc; they're just spikey metal throwing stars. (Mwahaha.)
Leon's gift is. . . okay, God knows what this is. It's sort of papery. . . well, almost leathery, very thin, eggplant, and with wierd regular holes pinpricked in it. There's a lot of it; it's sliced in thin dried piles and wrapped in leaves.
Jor gets. . . an ashtray. No, flip it over, Jor. There. Jor gets a strange wooden box. Inside, there's a natural-looking wooden stick. If the bole on one end and the little diamond on the other are compressed and twisted, it can be pulled into two nasty-looking knives with blades he hopefully didn't test with his fingers. The nifty thing, if he runs it through a metal detector or any scanners. . . it looks like a stick.
Becky gets a bracelet of carved stone and bone beads. It's not quite the right size, like the predator remembers her as slightly smaller, but the cords can be let out a bit at the end.
Spidey gets a nifty fossil of an alien creature.
It looks like messages can be sent, but people cannot travel to these coordinates.
