Which tower are you talking about? The only tower that I can think of with skeletons are the lizard skeletons which contain the braccus rex boots but that is almost halfway through act 1. As far as i know there was never an npc that gave a quest there. However, there are dead skeletons below the maze that sort of give a quest, and there is the skeleton covered in necro fire.
I've played since EA opened and I can't think of place that had what you are talking about. But I am still finding new things so i may be mistaken. Can you provide a screen shot of the tower you are talking about?
