However, he accepts the party's assurance that they are there to help, and quickly gives them instruction on what they need to do:
The other being here is a representation of the ship heart, its power and its personality;
They need to help push the power of the ship heart into the permanent shape the ship heart has set for it, while keeping the personality back
The logic of this is explained as: the personality knows what's impossible, but without the personality, the power of the ship heart may be capable of doing things that appear impossible
After Delicate Harmony has got over absorbing this revelation, the fight begins in earnest. The 'personality' of the ship heart seems to want to join the party and their new pentapodal friend, but it has no weapons nor abilities. The 'power' of the ship heart doesn't mind being pushed around by the players, but doesn't want to let the personality go - at any opportunity, they try to call it back to it.
The party are able to slowly shepherd the 'power' towards a pentagonal-shaped socket in the opposite wall, which appears intended for this purpose. It is a tough fight to get there, and the pentapodal hero goes down once but is healed by Budding Leaf. Delicate Harmony asks permission to Harvest the pentapodal hero, which he is confused by but agrees to - this gives Delicate Harmony the ability to forcibly pull the 'power' away from the 'personality' and into the 'socket,' while standing in the socket himself.
As the power is forced into the socket, the scene fades out, leaving a vision of the pentapodal hero curled on the floor of the original room, now containing a recognisable Gate and some rockwork creatures. He appears to once again be unaware of the party, but is sobbing lightly (yet happily?) and holds a blue gem in his hand which he did not have before. When Delicate Harmony attempts to interfere with this gem, he clutches it tightly like it is the only thing he is currently focused on.
A blaring alarm starts to go off, indicating that someone outside the holodeck is about to pull them out. The party eventually follow their training, stop interacting with the scene and wait for extraction
