If you're really gonna do this thang then do it properly
Ancient speaking teacher
Level 1 runes only
Quest is something which requires intelligence, not just walking around and picking up random items, and appropriate. Something like: A buncha new maps is made (I could do this) which are based on the rune that is obtained by completing it. e.g. lhor could just use irundar, solving the puzzles to get blessed water, then taking that back to the npc. But instead.. an npc at the end of each map who gives you an item, which you bring back to the other npc. Alternatively, the one at the end just teaches you the rune and the other npc is there just to tell you where the places are.
So it'd be kinda like (Conversations below would be in ancient):
Player: Hello
NPC: Greetings
Player: What do you do?
NPC: I know information about many unknown areas of these lands.
Player: Unknown areas.
NPC: Indeed, if you get me x I will share them with you.
So you bring back x.
Player: I have x.
NPC: Thanks very much. Now I can tell you where they are.
Player: Tell me where they are.
NPC: Do you wish to know about (Then a list of choices like: The ice cave, the fire cave, the illusion cave) etc. etc.
Player: I want to know about the fire cave.
NPC: The fire cave is In the east. You must pass by Silverbrand to get to it.
Player: What is in the fire cave?
NPC: I do not know what is in there, only where it is.
Then at the end of the cave you speak to the NPC and he's like.
Player: Hello
NPC: Greetings. Who are you?
Player: I am Gherkin the gollywog.
NPC: Nice to meet you.
Player: Who are you?
NPC: I am (insert name), the fire mage.
Player: Fire.
NPC: You would like me to teach you the rune of fire?
Player: Teach me the rune of fire.
NPC [anc]: RA BHONA
Player: Your master give you the power of the rune RA. You can feel that you are now able to control the power of this rune.
NPC: There, you know possess the rune of fire.
Hooray, a rune.
Then you have to get out again
These caves would be a good place to include other things too, there would be the one way which is the way to get the rune, and another way where you could put like.. fire elementals in the fire cave etc. But the straightforward route would just be puzzles with no need to fight anything.
