Short answer: maybe.
Long answer: There's another wave of content planned loosely for next year.... Maybe the lower level will get added than.... maybe.
There are a few places in the game where things were added to allow future content to be dovetailed into the game. Some of them were used. Some of them weren't. The game was developed over years, so plans changed.... or that's the story David the Developer keeps saying.
(Personally, I think the Developer has a friguld rum problem. Every time he passes out at the New Garand docks, he seems to forget the next part of the game. We tried to have an intervention, but he just turned out characters into Level 1 goblins.... Pesky old school Dungeon Masters think they're the gods of their little realities.... )
