Roots of Corruption: Infestation

From the front of book:

Two years ago, the city of Myth Drannor was overrun with vermin. While adventurers were able to purge the infestation, bigger problems at the time ensured few paid attention. Now an awfully familiar fungus spreads its tendrils through the ancient woodlands of Cormanthor and this time it’s proving harder to kill... A Living Forgotten Realms special adventure set in Myth Drannor for characters of the Heroic tier (levels 1-10).

This adventure is loosely connected with SPEC3-2 Roots of Corruption: Dark Seeds and SPEC1-3 Ghosts of the Past: Hive of Corruption.
