Where is that Rainbow Rock???

[Julian]

I have been running through the whole map and checked the maps in the walkthrough, but i still can't find Rainbow Rock.

There is no rock where it says so on the map.
Do i have cast a spell to see it or what?

Desperately need the help, have to finish the opening.

Never mind

I found that unimpressive pebble of a rock.
Would think it was a little bigger than a halfling

Now i know where it is, and i will never forget it
