Seamats are plants that float on the ocean waves. They were one of Harkon Armal's first creations in Culthet.(445) These plants can, over time, grow into great mats that are solid enough to support plant and animal life upon them, essentially creating small little floating islands. The mats draw nutrients from the ocean and in turn other plants are capable of drawing nutrients from the mats.

At times, when the conditions are just right, these mats can be pushed together by the waves. Their roots will tangle a little, allowing them to form a larger island. During this time animals are free to roam from island to island, as only a sliver of water separates them. However, these conglomerations do not last long and within a few hours the seamats drift away from each other again.
