Hm. I didn't bother to check EternalSword's sources, and even if I had, I still would've been misled... =P Well, we can always exploit Enworld's funky time-space continuum and say that Grenton mysteriously changed places, or perhaps the time ripples on the road to Allimon were especially heavy for the past week, and caused travelers to be diverted to Grenton in mere hours rather than days.
Or we can relocate KO's Grenton. This kind of thing is bound to come up in an PbP world, we just need to decide which location is canon, and handwave the other references away. Personally, I'm for keeping the original spot and chalking discrepancies up to the Enworphant.
On a completely unrelated note, all this talk about feat rogues and urban rangers has made me more aware of the barbarian totem variants. (I knew they existed before, but I never really read into them.) I'm not sure when they got approved, whether it was before or after I made Rasereit (my dwarven barbarian), but the Horse totem fits him so well, it's uncanny. What's the chance that he could change from standard barbarian to Horse barbarian this late in the game? Might a psychic reformation or the spending of DM credits sway your opinion in my favor?
