The second survey crew landed near the object embedded in the southern hemisphere of a dead world. They’d lost contact with the first team months ago.
The artifact resembled an enormous crystalline worm buried in the earth. A nearby cave led them down into a chamber filled with alien devices. Numerous bones lay scattered all around.

A portal was set into the construct, lined with spikes that sparkled like icicles.
They understood too late as the chamber began broadcasting black noise.
The worm was ready to feed.
(This drabble was submitted both to Drabblecast's drabble forum and to Sam's Dot Publishing "Drabbler #16" Contest, the theme of which is "Alien Architecture." Drabblecaster's are submitting some mighty good 100 word stories for this thus far. I hope some of us at least get in the magazine and earn a crisp new George Washington for all our hard drabbling.)
