Might And Magic 8: Day Of The Destroyer

Hint: The Obelisk Quest:
Go to Murmurwoods and wait until June 24. Between 5 a.m. and 9 a.m. look for the Unicorn King. Take the key from him and return to Ravenshore. Then, find the fenced in area.

Note: That you must have gone and collected all the Obelisk information first before going to Murmur Woods or the Unicorn King will not be there.

Hint: Hidden chests:
In Ravenshore, go to the bridge that separates the wolves from the centaurs. Look for a swamp tree beside it labeled "tree" and click it. It is a hidden and trapped treasure chest with a legendary weapon, shield or "clothing".

Just behind the ogre fortress, drop down inside the outer wall, just behind the actual building. Click around the wall to find a trapped chest that always contains some good loot.
