Green hell

The Green Hell is the name given to an enormous zone north of the charted map. This huge land has been only scarcely mapped, as it is both perilous in the extreme and quite confusing. For some strange reasons, using dimensional magic in the Green Hell often leads to unpredictable and often disastrous consequences, making the use of portals and gating almost impossible.

Very little can be said on this zone besides that it's extremely dangerous

Not only will you find plenty of predators such as giant nagas, but creatures that eat them as well.

the area north of the dimensional unstability spike at Deeper Felarya. The dimensional unstability manifests differently here, with the consequence that using dimensional magic in it becomes somewhat difficult, if not outright pointless for the least persistent. 

Despite its fecundity, large patches of the Green Hell are and stay clean of any trees for months. When it isn't forest fires, there's creatures that bring them down. It's only the swift rate of renewal that allows for a consistently forested zone. Where the trees are cleared, water tends to promptly gather, pool, and then swiftly stagnate, to the benefit of numerous varieties of insects and fungi. Even the trees seem to exude a greenish vapor that extends far above the canopy, coloring the lower clouds and giving this land its name.

The Green Hell's landscape changes quite often, due to the frequent forest fires that sweep through the landscape- one every 100 days, on average. The soil there is not just what it is anywhere else in the realm, but it also counts on a thick layer of rich ash-fortified humus. Further, the dimensional effects create an unique ambient where plants tend to grow much faster than they should, allowing for a staggering rate of renewal after every forest fire. The brutality of the land seems to come from the ground up here, and trees are amongst the victims of the hungry herbivores- or what passes for an herbivore in this place.

Plenty of the so-called herbivores are highly destructive to any trees unfortunate enough to be in their path- and while they're mainly green eaters, many of them are perfectly capable of processing more tightly-packed energy, which they do at the slightest provocation, for they're extremely aggressive as well. The creatures that prey on them know the risk better than anyone- and they're prepared to take risks on anything else as well.
