I'd love to play a super upbeat and enthusiastic tech-priest explorator who divides her time among pastoral care for the ship and helping them appreciate the great wonders of the Omnissiah, searching out lost technology in the Quest for Knowledge and making sure the Rogue Trader doesn't accidentally employ any heretek.

Basically, she's way too keen about the Omnissiah even for other tech-priests.  But since she's not broken any rules, she's just been shuffled off to some random place in the Imperium where she won't bother anyone.

'Alright, folks, who wants to share how the Omnissiah has helped them today?  Hm?'
