just a few questions:

1. what do Ordo Xenos Inquisitors look like?

2. In the empreor protects book, inquisitor zarith writes a letter to inquisitor quest and say's 'im sorry' at the end what did this mean in

the end because I think I missed it

3. any info on Tabius Rasa (the Feudel world) beacause I really want to do a mission of Feudel world in the Jerchio reach

but theres no info about any of these worlds, any help?

1) Inquisitors look like every other human in the universe. They're just people who have been given essentially unlimited power to protect the Imperium.

2) It's never gone into, from what I've read.

Inquisitors are usually Psykers who fit a certain psychological profile. They are skilled Interrogators and ply their Pskyer and interrogative powers to find Heretics and Cultists (Hereticus), Demons and their Summoners (Malleus), and Alien Sympathizers/Collaborators/Imperial Citizens dabbling in Xenos Tech (Xenos).

As to what they look like, if you read the Eisenhorn trilogywhich has examples of Hereticus and Xenos inquisitors, they are just like men and women. Men and women who have access to endless millions of credits worth of augments and technology. Their willingness to gain these surgical/chemical/prostetic benefits varies from one inquisitor to the next. One might happily trade away his body for augments or a permanent suit of Power Armor to walk around in. A beautiful, proud (and somewhat Vain) female Inquisitor may choose to only receive rejuvenant therapies to maintain her beauty and age for a few hundred years while she uses her potent Psyker powers to do her job. Some favor large Retinues, others walk the solitary road.

Of all the 40k archetypes, Inquisitors are actually rather varied. They are without a doubt very bad ass. You have to be bad ass to attain the rank of Inquisitor I imagine.

** MIGHT BE CONSIDERED A MINOR SPOILER **

@ 2) IIRC (having read the second mission some time ago) Quist suggested that there was some kind of quarrel between them when they've last seen each other (I remember getting the impression that it was a bit on the romantic side, but that could just be my imagination running unchecked). But as MILLANDSON said, no other info is available.
