Charac, why would humans have the right to enter the ruins?
(I mean, let's look at this guardian like on a computer security program, does it forbids every being from entering the ruins like a firewall, or does it have a definition of creatures it needs to fight like an anti-virus? And if it's the last case, then why go through the trouble of defining and not just forbid everybody to enter?)
Drake, I have worked out some of Shar's development:
First artifact: will be a set of 2 magical axes, they will be made from an indestructible alloy(maybe developed by local alchemists) and will tie themselves to Shar, as he is the one who absorbed the "Minotaurus", basically they can't be lost or stollen because they'll just re-appear in Shars hands at his will.They also will cary the axe superior fighter ablities with them, those abilities will be absorbed by Shar the first time he touches the artifact.
The second artifact: will be about protection and defence, it will turn Shar's hide as hard as forged steel, and so it will turn his horns and hoofs as hard as forged steel, it will also give him the regeneration ability (his wounds will heal fast, and if he happens to lose a limb, it will regenerate over time).
On the third artifact I think of going towards the immunity to hostile magic ability, and we will see from there..
What do you think?
