You know, with talk of inspiration, it occurs to me that the conversion itself might be a jumping-off point for the story. We know that Talashia's alchemist contact was doing Horrible Experiments, the result of which was the current chaos beast problem, but which by no means needs to be limited to that. I seem to recall us walling off a large room that looked full of bodies, for example.
One wonders if the endgame of "Those Left Behind" might not involve the culmination of those experiments and / or some sort of chaos-y build up from having this many chaos beasts in one place. I don't think I'd like 'transported to another world', but what if the net effect of what's going on is that the world (or perhaps just we) change on a fundamental level? It covers some of the smaller mechanical inconsitencies (class shifts and slightly different magic items, etc), but also allows for things like Uulark changing bodily into something else without our having to pretend he's always been something other than human.
Just brainstorming.

****************************
And back to my slow learning curve on 4e: how many healing surges are standard to have to use in the course of a day? Dyspeer has a lot more hit points and higher defenses than Shai, but only has 2 healing surges. I see that Rangers can Raise dead companions, so I assume the lower surges correlate to the lower Raise cost vs. humans, but from a character perspective, I can see Shai going more than a little nuts if he's constantly watching Dys die and having to raise him.
There's at least one power (Invigorate the beast) Shai can take that lets him heal Dys once a day 'as if he used a healing surge'. I assume that means he wouldn't actually need to use one. Shai had it earlier but I swapped it for the raven form. Are there other options like that? I'm thinking about switching Shai's paragon path to Sky Hunter to cover flying, and swapping back the Invigorate power, but I don't know if I'm being paranoid or not about Dyspeer's survival chances with only 2 surges?

On the actual game we're wrapping up: IG, are we waiting on the beasties to attack, or are you waiting on actions from one or more of us?
