Bastion of broken souls: is the interior dominant aligned?

[PairO'Dice Lost]

Basically what the title says. I'm DM'ing this... tomorrow, and when I read it for the life of me I can't tell if the characters are constantly healing while inside, or only in the " portion of the Positive Energy Plane where the Bastion is located"

Yep. See the sidebar on page 19:

Inside the Bastion, the visual brilliance of the Positive Energy Plane is absent, except as noted; however, the supercharging effect of too much positive energy remains, and must be dealt with.
