Adam had to go a long way to defeat the three Commanders and activate all the statues. All to see the External Artifact.
However, his goal was not the External Artifact but what was supposed to be hiding under the round platform.
All the time Adam was in the fortress, the black particles directed him downwards, there were no more paths further down in the fortress, and therefore Adam's monster had to be close to the External Artifact.
For this reason, despite his interest, Adam did not rush towards the stream of light coming out of the depths. He waited for a while, then cautiously stepped forward, keeping his full focus.
Silvana realized that the choice was made, now they had to get it right.
'The main thing is to take your time. Perhaps the monster is already waiting for you and ready to attack, or possibly your fight will be arranged by the External Artifact, who knows?'
Step. Step. Step.
