Silgrad Tower from the Ashes

In the Arena maps of Valenwood, there were four islands on the south coast. Now there are only three in all maps made sense. TOYB proposed that it could either be a stray Thrassian Sload kingdom (their islands tend to rise, sink and move from time to time) or a chunk of the seaweed-forest of Pyandonea that broke off and drifted towards Tamriel.

This claim is for either one or a series of books explaining the island, which should deal with where it came from, what it was like and what ultimately happened to it. The Arena and later maps can be found on http://www.imperial-library.info for reference.

Personally, I'd be in favour of it being ambiguous as to what the island is/was exactly, but having a cave off the smaller western isle with a Sload living in it (using that nice model that was made).

Sure, we can leave it ambiguous. Still, might be nice to have a book exploring the mystery at least. And definitely we should include a Sload.
