Forest of Mir Prior to the Spellplague , the Forest of Mir was a dense forest that covered the southern highlands of Tethyr and continued south over the Marching Mountains and into Calimshan . Names . The Forest of Mir was named after the lost elven kingdom of Keltomir and the later human First Kingdom of Mir . It had many other names . In ancient times , the elves called it Darthiir Wood ; in later times , they named it the Sarenestar . The gnomes who lived there called it the Timbemerald . To the humans of Tethyr the northern part of the forest within their country was referred to as the Great Highland Glade , while the Calishites called it Khalahmjiri , which was Alzhedo for " place of deadly teeth " , for all the monsters that lived there . Geography . The Forest of Mir covered the Marching Mountains north of Calimshan and spread over the land between the mountains and the trade road from Darromar to Saradush . Near Saradush , the forest bent sharply southward until it reached the Spider Swamp , forming an eastern border for Calimshan . A large portion of the forest in Tethyr was considered part of the Mir Protectorate . There was plenty of water in the forest . Small streams ran intermittently throughout , emptying into the Spider Swamp . The forest had hilly , rough terrain , which made passage of large groups difficult . Many trails passed through the forest , so getting lost was not as great a risk as being ambushed by monsters . Except for a few logging roads , the majority of these trails were game trails that led to ponds or streams and changed rapidly . Some of the forest inhabitants made use of treetop trails as well . Ecology . Flora . The forest consisted mostly of evergreen trees , growing in dense clusters , as well as some other dry - weather plants . The trees within the forest were far taller then any others found in the region , and they produced pine cones of legendary size . The trees continued south over the slopes of the Marching Mountains until an elevation of over two miles . Because of the hot weather of the region , the trees had roots as deep as 50 feet below the ground to reach water . Beneath the trees , the forest bed was covered in a thick underbrush . Fauna . Foxes , weasels , small rodents , and small songbirds made their homes in the forest . A wide assortment of owls lived in the northeaster regions . The southern stretches of the woods were the locale of panthers and other wild cats . Many snakes lived in the southern parts as well , especially as one moved closer to the Spider Swamp , as did a large number of wild boars . More dangerous beasts , such as stirge s , choke creeper s , bloodthorn s , and giant spider s , could also be found there . Climate . The Forest of Mir was stifling hot most of the year . The pine trees did little to cool the forest from the heat of the sun . Inhabitants . The Forest of Mir has always been known as a great hive of monster races , posing continual problems for both Tethyr and Calimshan . Goblin s were the most populous inhabitants , followed closely by ogre s and gnoll s . Historically , various kinds of giant s lived under the trees of Mir as well , though most of these lived along the northern slopes of the Marching Mountains in the west of the forest . Hydra s and green and black dragon s were uncommonly found , along with many sylvan creatures such as dryad s or satyr s . Near the Spider Swamp , aranea claimed a small region of territory . By 1370 DR , there was a growing population of drow in the forest . The first rumors of this occurred in 1346 DR . The original reported numbers of a population of 80 , 000 drow were larger than the truth , which was that three settlements existed with a combined population of around 6 , 500 . These three settlements were Dallnothax , Iskasshyoll , and Holldaybim . All three were located along the foothills of the Marching Mountains . More than 70 % of these drow are exiles from the Underdark and worship Vhaeraun instead of Lolth . Some human settlements rested at the very edges of the forest , but the villagers never ventured more than a mile or two into the forest . The forest was home to a settlement of wereboar s in the southeast . Rumors also spoke of a magically hidden elven city within the forest where gnome s , elves , and escaped slaves live in peace . History . Formation . Originally the forest was part of the massive Keltormir , which covered the whole region of what later became Tethyr , but " circa " - 8500 DR it was sundered by dragon fires into a separate forest called Darthiir Wood . During the First Kingdom of Mir , the forest shrank to its current borders , from fires caused by war with the beholder s of the Lake of Steam region " circa " - 1550 DR . Post Spellplague . The Spellplague changed the trees within the forest into huge stone spires . The region became known as the Spires of Mir . Rumors and Legends . It was said that the drow of the forest maintained tunnels below the forest floor the connected to their vast network of such tunnels within the Underdark . The majority of Calim ' s riches were said to be hidden in an extradimensional palace located in the forest and guarded by an ancient crystal dragon named Klaruuotur and several djinn . Two mythal s remained in the Forest of Myr . The first was located in Myth Unnohyr . Less than two dozen sages had ever heard of it , and only two knew of the treasures of Keltomir it still contained . The second was Myth Dyraalis . While hidden to most , in truth , the site was still a thriving town of elves and gnomes and escaped slaves . The mythal was centered in the Mother Tree , and its magic cloaked the town from discovery . Finally , legends told of a crystal - blue pool of eternal life , the Wellspring Endless , said to be found deep within the forest . If a true tale , the pool remained lost .
