Corruption of the Forgone Fens

The corruption of the Forgone Fens was a catastrophic event that took place in Visaerie, originating in The Forgone Fens, on the 22nd of Junbutor, 5th Titanil 1034, 2E; it continued to spread until the source was destroyed on the 12th of Vloekus. It poisoned the land, turning many people into undead, and unleashing demon-like creatures from the portal that brought it about.
==Description==
The corruption of the Forgone Fens was caused by the opening of a portal underneath the Temple In The Swamp by an orcish warlock using Demon Seals. As the portal opened, the swamp fell into ruin, tinting purple, and all life around it died as the corruption spread. The corruption turned many into undead, and the portal let through many demon-like creatures.

===The Onyx Portal===
====Session 14====
A strange power began to form within the Forgone Fens which seemed to spread rapidly, killing everything in its tracks, mutating any living creature it reached. Tight on money, King Otrix Roseforge II decided that it would be best to task the Vis Mages' Guild to deal with this issue, while, in order to protect the capital, locking the gates of Vis on all sides.
This angered the populace as they felt as though the king was leaving them for dead, sparking the fires of revolution and kicking off the Quarry Rebellion.
====Session 15/16====
The Party, realising the corruption would continue to spread if not dealt with, rushed back to the Forgone Fens. They fought an enormous creature with many tentacles, and managed to break the core of the portal, revealing an onyx statuette. After the portal was broken and closed, the corruption halted its spread, but the effects would not fade away so quickly.
