Ruin elemental

Ruin elementals were fearsome elementals summoned by ruin chanters to protect their homes.

Description
Ruin elementals were massive earth elementals approximately tall and  in weight. They were composed of rubble from the ruins they guarded. Over time, this rubble slowly eroded into smaller pieces, so that the oldest ruin elementals appeared to be composed of gravel.

Behavior
Ruin elementals cared for nothing except protecting the fallen cities and fortresses they were set to guard. When those areas were not threatened, they were relatively benign.

Ecology
Ruin elementals existed to protect ruins wherever they might be. Thus, these creatures could be found in tundras, deserts, and other hospitable and inhospitable places. Due to their remote dwelling places, they were little more than legends to most of Faerûn.

History
Factions of the Zhentarim and Red Wizards were known to seek places where ruin elementals might be found, and would pay well for information leading to such places.
