On the Trail of Imirix
Tower on the Witchlight Fens
A ruined stronghold on the fens
On the eastern edge of the Witchlight Fens, not far from the ruins of Kalton Manor and the western edge of the Harken Forest sits the Ghost Tower, as the party has come to call it. It contains a scything blade trap room near the entrance (which they can learn to operate and fix up into better condition) as well as an interior room that can be secured with a three part magic key.
Down a ladder under a sarcophagus in the main crypt is the Room of Pools.
There is also a set of rooms covered with broken and not-broken alchemical equipment and an adjoining room with a deep pit where the party encounterd some death jump spiders. They have not yet explored the pit.
