A large tower situated atop a hill looking steeply down on the northern edge of New Velar‘s coastline. Once belonging to Erethun Rivenstave; when the top floor disappeared, the remaining four floors- and the land hill upon which the tower sat- were inherited by Erethun’s son Lucus. Decades later, after Lucus had grown old and given up on finding the secret of his father’s mysterious fate, he sold the tower and the property to Tremin Aldbryte.
Dank, dirty and untended, the warlock, Slivgren, broke in and used it as a base of operations, using flaming skulls and eventually zombies to ward against intruders.
In a battle on the fourth floor- ostensibly a roof, now- Slivgren was defeated despite the help of a summoned demon. As a reward for their service the PCs were given the deed to the tower and have begun cleaning it out, two of them, Lily and Griff, going so far as to take up residence there.
