An excellent submission, I echo the praise of the others. I don't really have any questions after reading this. It seems like any of the pocket realms would be easy enough to devise of your own, but I do look forward to reading more of this setting.
Oddly enough I read this two days ago and seemed to not have voted or commented on it at all. I like it, the backstory is quirky and detailed enough from a single perspective it reminds me of why I love backstory. Even though it might not be a story that the players will ever find out it is still a much needed bit of context to any sub I think. Kudos to you.
Interesting. Liked the idea of the Tower creation leading to the city's end and the quest by the Wizard-Lichs to free their torment.
Question though, would this mean that there are towers in every pocketworld? In my mind the tower(s) act as gates from one world/dimension to another. As I followed the plot I expected the characters to end up at one of these towers, not a hill. Or, is the tallest hill that dimensions version of the tower?
Pretty much everything has been said already; it's an interesting premise and a solid submission. I especially liked the writing for the internal dialogs of each character, because they really make it come alive. I actually feel bad for the wizards, though my normal inclination would be to dismiss them entirely as arrogant fools. Well done!
If Kevin Costner and Morgan Freeman can do it why not a croc?
Solid idea and an amuzing one at that...might be a shark jumper for a campaign though...once the PC realize the GM is open to launching animals at each other as form of warfare things threaten to get all Monty Python on ya.
