It's a tabletop RPG like D&D, only where D&D evolved from edition 3.5 to 4, Pathfinders stopped at 3.5 and turned left at the fork in the road. They're publishing their first official rulebook (it's been in test play for about a year, there a pdf on http://paizo.com/paizo if you're interested).

The world I'm going to be playing with is in a new age. In the age before, most of the planet was covered with Dark Ice. Some Immortals were trapped in the ice and evil magic-users could tap the immortals' power.

I think I'm playing a half-elf druid.
