Ni stykker kreves for å unlocke The Companion og frigjøre planetaren som er fanget i den. Beskrivelse fra DiA, p. 122: > Each one weichs 3 pounds and is engraved with runes that spell out the words "Solar Insidiator Lock" in Infernal, followed by a number from 1 to 9. [[Mad Maggie]] besitter én, men vet ikke hva det er. Flere er enda i the Crashed Flying Fortress. Noen har blitt scavenged, og er rundt om i Avernus. Fra [[The Avernian Quest]], "Rods, Rods, Everywhere": > As written, all nine adamantine control rods are located in the wrecked flying fortress. Alternatively, the fortress could have been looted decades ago and the rods scattered across the Avernian plains. Maybe [[Zariel]] has recovered some and they’re in her current fortress; maybe Bel has some; maybe some warlords prize them; maybe [[Mad Maggie]] has one and doesn’t even know what it is (the PCs see it early in the campaign and later realize – OMG! – it was right in front of them the whole time!).
