Graelliscy

Graelliscy was a planet with an unusual graviatation pull.

History
Humans first settled on Graelliscy at the end of the 45th century, but it took them years to adapt to the planet. Beautiful cities on floating islands were built in the skies, making the most of the planet's gravitational oull. As everything floated in the air during the summer, but gravity would increase in the winter, pulling the islands towards the ground. In early 4826, the Dalek's unending march through the universe spread to Graelliscy.

An airbourne attack was the natural approach, but the Daleks underestimated the sky city's defences, with their gun towers picking the Daleks off with ease. After regrouping and assessing the situation further, the Daleks realised their only chance was to take out the central control station. They attacked again, focusing all their fire on the main island, trying to break through it's defensive shield. They fought long and hard, finally bringing down the power source for the shields. The Daleks then commenced the massacre, exterminating everyone in site, within days the Dalek's were victorius. (DWBIT: #25)
