At the scene, besides this altar, no other items for extracting subspace power can be found. It seems that even the Heretics are very cautious about using the chaotic power of subspace. Considering the R-9 base is filled with researchers not accepted by the outside world, their restraint likely stems from a warning at the intellectual level.
Of course, more likely, the reason is that although the subspace fracture before us is enormous in scale, it has been sealed and suppressed for the past millennium, preventing it from large-scale releasing chaotic power. The pale light restraining the subspace fracture clearly has a purifying effect.
It's exceedingly difficult for the Heretics to extract usable subspace power here.
