Firethorn

Firethorn, or Sea Rose, was a naturally occurring plant on the Island of the Firethorns within the Genie's Turban off the coast of mainland Zakhara.

Description
The presence of firethorn gave the Island of the Firethorns a lovely red coloration. Though beautiful, the firethorn plant's thorns carried a dangerous poison, creating a natural barrier that surrounded most of the lower portions of the island since the plants grew so close together. Firethorn plants also gave off natural heat and glowed softly.
