Really, no one should be building a stronghold just to control portions of the weather. It leads to all sorts of problems later on. The latest preview for EverQuest II demonstrates just that, because while Karana, the Rain Keeper, might have had the best of intentions, it turns out that even tucking your Bastion of Thunder away in the Plane of Storms doesn’t prevent people from rushing in and taking control of stuff. And of course it contains four aspects of storms tied to four towers and guarded by storm giants, because now the towers (and, by extension, the storm giants) are in notable danger.
Needless to say, players will be expected to go in and fight against the Tenets of Hate to make sure that nothing bad happen, which means braving both those enemies and the storm giants. There must have been a safer and less ostentatious option for building a weather control facility, Karana; maybe something that looked more like an old convenience store would have brought less attention.
