Dragon Horde

Is there a map for Dragon Horde?  I have 7 dragon keys.  I know I need the one from Scorpion but can't break the thorns.  I need the one from Smugglers but can't break the ice.  Then I need the one from Dragon Horde but I don't have the location.  Any help is welcome.

there is one you find in box later depending on level

Smugglers key is not behind the Ice, it is behind something else in another room. 
Dragon horde is a final fight with a group of dragons around a huge fire, put the fire out. I think you have to open a door/chest or 2 to find the dragons and fire, have not done it in a long time. 

amazing

If I remember right, you only need to fight 12 dragon mobs, not the full 22, to reach the key.  I too, haven't done dragons horde, in a long, long time.
