Background:
Krassa. Perhaps a wood name. Krassa, the only man, walking side by side with the wild elves of the forests. Not too often, elves take in custody other race's child, to shield the young from the destiny of their fathers, or just for causality. Krassa was one of those cases, he appeared one day in the forests, lost, barely walking, hungry, but alive. The druids of the local Druidic community adopted the child, as they sensed in him, a powerful connection with the powers of nature. How did the boy survived the harsh of the forest for so many days, the elves didn't know. Krassa developed a strange fascination with plants and fungi, something most druids do, but just at certain level. Most of them feel more attracted to a diversity animals, who can also make something to protect the forest more actively.
But not Krassa. The only human in the Druidic community, and also, the only druid that didn't get along with animals.
When the ritual in which Krassa was to commune with nature in extreme, in which his bond with the Powers would be complete, he proved again, to be unique.
Most druids adopt the shape of the primal beast first, to morph into the animal with which they have a special connection, like a bear, or a wolf. But Krassa's primal beast form was fleet. After only a few minutes, Krassa's body morphed into a mass of shifting vegetation! He resembled a Shambling mound to most of the druids present, including the high druid. After our young druid finished his transformation, the High Druid approached him. Krassa's master feared the reaction of the old druid. Krassa himself lowered his head, trying not to look at the elder in the eyes. But the High druid's word surprised them all. "My dear child, you, as nature itself, are extraordinary surprising"
With the blessing of the elders, Krassa decided to leave his home in the heart of the forests, and wander the land. His fascination for plants led him to journey to any forests of which he had knowledge of. With him, he carries a big heavy book, in which he notes every specimen, with draws and descriptions, and also it's uses, if any. He hopes to write a huge catalogue of plants, that covers from the smallest grass to the tallest tree.
Well, up to here, what do you think? I want to know, if the background should include the scene in the beach, or if the replacement is to come from a different place; so I can finish it up.
Also, I took the liberty to flavour powers, according to the "plant shape" of Krassa. Anyway, I'll note the actual power, and then the flavour.
