Speculation Specialist Wizard
Because D&D Beyond is owned by WotC, part of me is screaming that this can't be a mistake (other than the typo).Considering "Athaspace" has a typo ("Wilspace") and "Doomspace" does not ("Wildspace"), I'd bet the latter is the final version. Though that raises the question of whether "Doomspace" is really Dark Sun or not...
But because I know Nathan Stewart leaned into the "Spelljammer Confirmed!" joke, a big part of me is thinking they're messing with us.
