His body is specially adapted to the cold like no other dragon in the clan. As such it was him who first swam down with Eigh-shruth to anchor the iceberg in place and begin carving out the hibernal dens below. Only after he managed to coax some of the more fire-inclined dragons such as Hephaestus to swim down and begin warming up the cave did the trip become worth it for the average dragon.

Plunge works closely with Solar, who is slightly more knowledgeable in the building habits of light dragons. Plunge works best with ice, snow, and frozen tundra but he's learning from the research Solar shares and is getting better at building a home into the ruins.
