Voadam inspects the rune. After intense visual scrutiny, it seems the rune--and probably the other intact rune gracing the northern doors--is a word from a foreign tongue, a pictograph or symbol, perhaps. If the rune could be deciphered then perhaps the door affixed to the rune could also be opened--without resorting to use of the wand. Whatever the case, Voadam is utterly unfamiliar with the tongue in which the rune is scribed and so, it seems, are the others in the group.
Having seen the ball of fire explode in the hexagonal chamber a few short minutes ago, Gamad has the strong suspicion that the gems are tied to magic of one variety or another. The vagaries of the spellcraft entailed are, however, beyond his ken. Despite his lack of understanding, several oddities of the explosion stand out in memory. The first oddity is that the green gem first vibrated at Maelicent's initial approach. The second is that after the explosion, one third of the eastern rune vanished. The third is that nothing happened when Voadam touched the star sapphire. The fourth oddity is that when the rod segment was tapped to the star sapphire, not only did the southern doors open, but none of the rune was erased, no ill effect was felt by Gamad, and the silver star shape inside the gem vanished.
To recap, that croc is 20 feet long. It looks like a young adult male; it'll be heavy. Let me know if you all have it settled to gut the croc, and if so, who (if anyone) is standing guard, where they are watching, and who is doing the gutting.
