The Truth About Monsters: Ents
The physical description of Ents that Professor Tolkien gave us in The Lord of the Rings is spot on. These “tree shepherds” are roughly humanoid looking trees themselves. Any sort of tree can be represented, with the deciduous species being the most common.
What the good professor got wrong was how talkative Ents are. They are not the slow and excruciatingly deliberate speakers they were portrayed as. Indeed, most Ents will talk your leg off given half a chance. Depending upon how great a hurry you are in, this can be either good or bad.
Among themselves, Ents speak by rustling their leaves and creaking their branches. With other species, they speak the Common tongue. Ents are also great gossips and a treasure trove of useful information, which is why most other sentients seek them out. The secret to getting the good info is patience. Ents are easily set off on tangents and can take a good long while to get back to the main topic.
Ents are also big on songs and poems, many of which relate events centuries past. You can learn a lot from these, if you have a few hours to spare. It was in fact the Entish story of Old Roughbark and the Great Flood that helped the Adventurers Five find the lost tomb of the Golden Emperor. Of course, the telling of the tale did take nearly 9 hours.
Ents are almost always found in groups of 10-30 in the deepest parts of old growth forests. They are found in every climatic zone that such forests exist. Young Ents, those under a century old, often wander into less dense forests or even lightly wooded areas.
