I've found some lime rock and an unopenable casket.
Where I'm stuck:
I've also come across a white dove which is being attacked. I can't free it nor protect it from its attacker.
There's an evil creature in a pool. I've tried pouring the lime into the pool in various ways, no luck.
There are both a temple and a workshop in the description, but I don't seem to be able to do anything with either of them (SEARCH, EXAMINE, ENTER, CLIMB, GO etc.)
There's a river which I'm able to drown in - weee!
Finally there are two guardians I need to get past, but I guess this relates to saving the bird somehow.
Help me
