Go ahead and commune with the world spirit in the statues. Preferably from somewhere safe like the navigator's sanctum.
You enter the Navigator tower, your sanctuary on the ship with much more cat beds and fewer decorative skulls than the typical Imperial sanctum. If you have any actual cats this is probably where they spend there time, safely away from your dragon pet that may mistake them for a snack. Here you follow the example of the last Eldar that communed with the World Spirit.
You find yourself in the Void, the light of the stars and sun of this world as a backdrop. Before you is a gestalt of souls. At first they seem chaotic, with spirits moving at random in a bright ball of light, but the longer the look the more you find a pattern emerge. You see a face appear, then a full head, composed of countless whirling souls. The end result looks something like an Eldar made from light pouring through mist, wearing a long robe of starlight.
A million voices begin to speak to you in your native tongue. Inconveniently they speak not as one, but each soul speaks with its own voice. Their message is the same with different wording. Some polite, some rude, some urgent, some relaxed, some worried, some calm, with the subtlety of the Eldar language allowing for a full spectrum of tone a human tongue could not hope to grasp. It takes you little effort to discern the voices from one another.
"What is it that you want?"
"Why do you disturb us"
"Thank you for freeing us, the sooner I'm away from those humans the better."
"Don't let the Dead Emperor devour us. I don't trust these mon-key."
"The agents of the greatest pervert are much worse..."
Start Warp preparations.
Your men prepare for Warp jump, moving all the mechanisms in place and performing the proper sermons and rituals. Prayer blasts over your speaker systems to insure the safety of everyone's souls, while your house guards ready tier weapons and shields at the designated checkpoints to insure the safety of everyone's bodies.
You have a new pilot - Rouri - who will likely steer better than you (especially if you are watching close and providing advice on the idiosyncrasies of your ship), but it is ultimately up to you who guides the
Ark Royal through the Warp. You are prepared to jump when the Eldar gives the word.
