We made a mistake.

What was once a terrible toxic miasma, we turned into a terrible toxic AND necrotic miasma. We cranked the danger to 11. Now, not only does it kill things... it brings them back.

After the original breach of the Temple of Haluu, The Guild and its Crows did their best to try and contain the toxic gasses that crept their way to our shores. We found the real solution too late. 

Way too late.

Undead twisted versions of Ursera's wild life can now be found roaming the zones, and is one of the Crow's primary concerns when scavaging for relics. The twisted miasma has covered about 60% of the planet now... weaving in and out of different areas over time. If only we found the Moonlight faster.
