GateWorld has expanded the photo gallery for “The Tower,” an upcoming episode of Stargate Atlantis. The episode guest stars Peter Woodward (the Technomage Galen on Crusade) and Jay Brazeau (Harlan in the SG-1 episodes “Tin Man” and “Double Jeopardy”).

Beware of spoilers!

In the episode the team stumbles across a planet with a massive tower built by the Ancients — a duplicate of Atlantis’s central control tower. There the Lord Protector (Brazeau) keeps his people safe using the Ancient control chair. But the Ancient gene is fading with each new generation.

When it is discovered that Colonel Sheppard has the gene, the leaders hope that he will marry the Lord Protector’s daughter to keep the line going. But her brother and heir to the throne won’t give up his birthright so easily.

“The Tower” premieres Friday, February 3 at 9 p.m. Eastern/Pacific on The SCI FI Channel in the U.S.!
