Beginner stumped already lol ( circle of rocks )

[FireBall]

I've stood in this rock circle and need to call a guardian. Threw rocks, pounded on door with bone, searched for hidden buttons.... HELP ! How can I get this guy's
attention ?

You should explore the rest of the area first. Maybe you find something that helps you.

Well, back long long ago during the times of Swords and Arrows, there were no cellphones to use to call for help. However, they did use a Horn to call for stuff

Ahaaaa ! So THAT's what that "Horn of Summoning is for ? " Thank you, I finally figured out a bit more exploring was in order and did find it down in the dungeon.
Only took me an hour to wise up. Heehee.

And, by the way, those darn trees killed 2 of my team before I chopped them. Thank goodness for the blue crystal, eh ?

Oh dear - I have a feeling you're going to be giving up on this game pretty quickly.
