Phijax III

Philjax was a cold, inhospitable planet. Nine-tenths of the surface was covered by a vast ocean.

History
In 9000 A.D., the Daleks invaded the planet. While exploring, an advance Dalek squad encountered a colony of giant squids, the monstrous Squeeth, resulting in a long and brutal battle. The Daleks refused to admit defeat and after days of battle, the Squeeth buckled under the sheer number of Daleks, battle-weary from relentless firepower. (DWBIT: #9)

''A Cyberman from Pete's World is also seen during the battle. It is possible that this Cybermen is another that escaped the Void after the Battle of Canary Wharf, like the Cybermen in The Next Doctor, or one of the space-faring Cybermen seen in The Pandorica Opens.''
