Evils of Land Bound to Darkness
Some 3000 years ago the elves in the region though about building a new empire in the forest but something happen and the elves all perished and has such very few people enter the forest and it has grown large untamed and unsafe for travel. Their was once a portal linking the elven citys but over the last 300-500 years it has begun to mall function and wizards have no reason to repair it.
The last group to go though the portal and explore the area was lost only one young kid(One of elves had a kid on the trip). He was told by his mom to tell them do let know one go into the forest and he was teleported to the holy temple of peylor in xiina. Some believe he must be the child of eska anar a famous elf cleric of paylor that was the first to create the Holy sun of Paylor to fight the rise of the undead king Marlor ndengina Some 300 years ago.
