The Queen of Thorns

The Queen of Thorns, the Mother of Frost, the ever-present force of nature that looms over FrostFern, threatening it's entire expanse with her desire for destruction.

Wraithroot
Wraithroot is the name of the mossy 'infection' spread by the Queen of Thorns to creatures across FrostFern. It grows across the bodies of it's hosts, changing their behaviors, and forcing their subservience to the Queen.

Long term infection by the Wraithroot results in the host being reduced to little more than a mangled mossy lump.
