You can find the first Elven Guard at the entrance to a valley just north of the monolith on the western edge of the Golden Coast
Once you talk to him, he asks you to see the Elven Guard at the entrance to the Forgotten Gardens. He also asks you to kill as many Kobolds as you can while going there.
Drive the Kobolds from the canyon!
I'm sure you've noticed that the canyon is infested with Kobolds. More and more of those horrible little beasts turn up here every day. Even the Priestesses of the Seraphim can't stroll through their gardens untroubled.
If you visit the gardens then please kill as many Kobolds as possible on your way. Report to the sentry at the garden entrance when you arrive.
You encounter a lot of Kobolds as well as a couple of Boars on the way.
You complete the quest by talking to the second Elven Guard who is at the entrance to the Forgotten Gardens.
Ah! You certainly killed a lot of those little beggars! Not that it will help much, they multiply faster than we can kill them!
Don't you worry about that through, here is the bounty that you were promised.
A guard has asked me to clear the path to the Gardens of the Seraphim and drive the Kobolds from the canyon.
I have killed enough of the little beasts. I should report to the sentry at the gardens.
Now that I have finished my work I can take a look around the gardens.
