The Book of Life: Proverbs, 10:8.

Lunism requires three truths to be presented before something becomes irrefutable. I will do that now.

First: in the story of Lun leaving Alastere, he left a number of relics in the hands of the heroes to aid them.

One such relic was a gold watch, so that one using it may pay the debt of time. The Demis Watch. Last known in the possession of Ion, but never brought out for display for risk of it being stolen.

...

This device matches the description of such a device. You've paid blood for all of us gaining that which is most precious: time.

It's unlikely if you stole it you would be so accepted in Ion, so we can infer it was given to you. A humble priest.

A fair observation.

Second: on the airship, when fighting the elementals, you called and wielded a blade, after the rest of the group had fallen.

Lunist Priests are not allowed to carry or wield weapons. Your tattoos are thus in conflict with your actions.

K'Sarian...

Third: you have the ability to call an Ionian diplomatic shuttle, via a star-whale. A low-level priest would have no such ability.

You speak of paperwork for its use, so you likely have not stolen its use either, but rather, been granted its use in emergency situations.

Thus, I have proven three inconsistencies between your story and your actions. The proof is inarguable.

You are bound by the terms of your pathfinding to never lie to any of us. So what is it, 'priest'?

Who are you, really?

...

I have not, and I will not, lie to any of you.

This is gettin' good!
