For those of you unaware, Jagex released today a new item called the "Stone of Binding" which can be bought from the Magic Guild for 500,000 coins. You can see more details on it here. Particularly of note is it's examine text: "A magical stone that can reform itself if combined with mystical energy."
While this was introduced exclusively as a way to create Tectonic Armour when combined with Vorago's primary drop, tectonic energy, the stones themselves show a great deal of potential for uses in roleplay, and likely will never get any degree of lore associated with them.
So, I pose this question to you: What should we make of them? Should we take itthat they're some rare artefact discovered by the guild, or simply a stone/gem enchanted by the Mages in such a way to react highly to other energies? Either way, I'd like to hear your thoughts on them. Keep in mind, the price may be a gameplay mechanic, but it does apply, in a sense. They're more valuable than any purchasable Dragon weapons.
