First off, your inventory should look like this:
Also bring a bow and arrowsYou should bring melee, and use armour with much defence.
Once ready, use the ::home command.
Click the entrance.
Once in, walk a few steps:
Click the room at the top and your character will run all the way through.
Turn on protect from range and any other combat spells, then go down the hole.
Once in: do the following.
What you need to do is corral the warriors so you can fight the queen alone, to do this, get all of them on you and run counterclockwise around the area in the center and try to get them stuck on it.
If done correctly, it should look like this:
As you can see, my Queen got stuck, this is what the bow is for.
The queen's main attack is range, but she does use a mage attack occasionally. Her max hit with the magic attack is around 40, so don't get cocky.
