ok, then incorporating the fact it ages the person atleast 2 years...
and is only time stop haste and slow be his only chronomancy spells, you are probably going to have to find what spells a chronomancer uses.
so When I see Prismal's wormhole, I'll know there is a real chronomancer.

Firstly haste and slow are not chronomancy, haste is a transmutation spell that makes you a few years older in AD&D 2nd edition and even in 3.5 it still is transmutation, you are changing your body to make yourself faster, you aren't slowing time down for everyone, and time-stop is the exact same way, you make yourself so fast, everything seems to slow down, so a protection from time-stop spell doesn't really make sense, since you are protecting yourself from someone augmenting themselves.  Try and find the 4 books of magic for AD&D second edition and look for Prismal, and Prismal's wormhole etc... that is a chronomancer,  and the school of force and so forth, is in a few rare 2nd edition magic books if you can find it, ranging from magic missle to the bigby hands etc...

Now that you have a general idea of what your npc mod
Stronghold (location) and quests (if you are using my suggestions)
NPC and Kit (probably still under development)
Now it is dialogue and banters (needs to be done)
good luck if you need any ideas on banters PM me I am going to relax away from my computer screen.

Perhaps in one of the tents in trademeet have a secret passage that leads to the monastary ( it would require Jinn to find it of course) and then use the whatever map(s) you find you'd like to use in order to get a good feel on what a monastary should look like.
so if you don't look for the monastary you won't get it, it would require actual adventuring/looking for it.

Ok if there is a monastary, there would be monastary quests
ideas...
1) Evil parties Petition to join
2) Evil parties attempt to raid the monastary
3) Neutral parties seek comprimise
4) Good parties raid the monastary
5) Radiant Heart seeks to end the world of the "evil taint" the monastary gives off
6) infighting between members
