Under Deepspace 5-07 and 5-08: MC discovers that the energy in her heart is an Aether Core and that this connects to EVER's experiments on her. This implicitly links back to Onychinus, which has been dealing in modified Protocores and disappearing Evolvers. The connection is still indirect at this point in the story, but it establishes the thread that will draw MC to deliberately enter N109 in the Long-Awaited Revelry arc.
