Tora's Secret Lab

Tora was an Ancient Scientist that loved to experiment with cross-breeding... and she had a secret lab in the city, where she conducted these horrible genetic experiments. In "The Cloaked Threat" the expedition finds this lab and the many creatures inside it, and a group of invisible alien-like creatures are accidentally let out.

In the "Halloween" two-parter, a Wraith that Sheppard nicknames Maggie invades the city together with her underlings and henchmen. Maggie somehow knows about the secret lab, and part of the reason she invaded Atlantis is to get to this lab.

Though Tora's lab is not seen in "Cold Echo", more of her experiments are encountered.
