It had only taken a couple of misunderstandings and re-explanations for Nova to understand:

Zenderael and Earth were connected! He could go home! An even more fantastic turn of events after the already-fantastic turn of events of having been returned to life!

Since he had no way of actually telling a warp mage where he wanted to go, he had asked Irena to write the word Omghan on a piece of paper so he could simply show it to them and ask to be sent there. The Nenakret, he knew enough landmarks to describe.

That should be enough to get him home. And then, and then...

And then he would see Chisaki! And Iravati! And everything would be wonderful and there would be no more problems ever.

In a nutshell, if Ravindra was exuding darkness, Nova was shooting off beams of light at the moment.

He was delighted to spot a familiar face, even in its familiar state of gloom. That was Ravindra through and through. He couldn't shout his name the way he normally would, but that was no problem!

"My favorite grumpy paladin!" Nova cried, descending on Ravindra and attempting to scoop him up in a hug.
