Marta

Marta was a young Athosian woman born and raised on the planet Athos.

After the Wraith attacked her homeworld, she fled with most of the survivors to Atlantis. Sometime after, she witnessed a shadow of somesort and informed Teyla. She took her to see Dr. Weir and told her of the event. Though skeptical at first, Marta's claims were true, after Jinto released a Shadow creature that was running loose in Atlantis.
