The Sylvan Class
The Sylvan guild was founded in modern times by those taking knowledge from both the Druids and the Magi of Achaea. They generally hail from the forest village of Eleusis, and exhibit both a deep reverence for nature and a profound curiosity about the base workings of reality. A typical Sylvan is in love with the forests and with those beings of the forest, but beyond that, they are scholars of nature who seek to better understand how to live in harmony with it by employing the basic elements - fire, water, air, earth - to help them.
In battle, the power of a Sylvan is often dependent on whether he's in the forest or not. In the forest, a Sylvan is extremely powerful, while his power fades some outside of the forest. This is because one of the most important things a Sylvan does is establish a Grove in the forest from which his power flows. A Grove is a location devoted solely to a particular Sylvan or Druid, and within his Grove, a Sylvan is nigh-undefeatable. He may call down lightning, summon swarms of bees, call up an earth golem, order the very forest to rise against enemies, and even resurrect the dead. Beyond providing a Sylvan with his Grove, the forest provides a Sylvan with a bounty of herbs to harvest, with which he may concoct helpful healing and defensive salves and elixirs.
Beyond these forest-related skills, the Sylvan possesses the power of the elements. By manipulating these fundamental building blocks of reality, he may transform himself into a Viridian - a living being of the forest, conjure fiery holocausts, call up a rainstorm, or summon an aerial servant to carry him into the skies.
