Anyone get the suspicion that the Oort might be the D’ni by a different name?
Mysteriously dead or gone civilization
Remnants of their civilization are strewn about many, many worlds.
Said worlds are connected via portals
Many of those worlds are very …unique, and possibly obey different laws
They use an interesting runic (and probably highly structured) numeric system
They’re viewed as largely benevolent
Did the Oort, perhaps, make all these worlds we’re playing on?
