Voadam cleans his blade and the coin both. When he judges it safe to handle with bare hands, the Green Wizard plucks the coin from its polishing rag and flips it over, all while Gamad leans over his shoulder with picqued interest.
Rolled a 1 on Gamad's spellcraft check. Not an instant failure but not enough to know much.
If Voadam hadn't insisted on the coin being magical and scraping it from the murky pool with the short sword, Gamad might have missed the coin's magical property or dismissed it as a trick of the water. To the untrained eye, the coin is a broad three inches in diameter with a milligrained beveled edge. Inset in the center on one side is a dragon eating its tail. On the other side of the coin rests an imprint of a great tree, its roots and limbs exposed. Certainly, the coin is minted of no current ruling body or organization native to Teggest, nor are the imprints recognized by Chev, Gamad, or Voadam. Brakkus, however, recognizes the tree, though not the wyrm eating its own tail.
Rolled better on the Knowledge (arcana) check for Gamad.
Gamad catches a glimpse of the back of the water snake as the creature surfaces yet again to feed on the algae floating on the pool's surface. The creature looks inherently un-magical to his trained eye. An eel, perhaps.
Unmolested by the three slugs working the dung and mushroom heaps in the cavern, the foursome at length joins Maelicent inside the owlbear antechamber. The gold coin illuminates the masonry of the chamber in soft peals of flickering gilt light. The goblin, having called for the group then ducking back inside, stands in front of a large set of double stone doors at the end of a short arched hall. Gamad recognizes dwarvish work when he sees it, and good quality at that. The hands that hewed this stone were old, indeed; the seams are perfectly mated, and the doors' hinges dovetailed inside a silent floating style inset on the room's other side. The doors open inward. Devoid of any visible locking mechanism or even an inscription, just how to get the doors open remains a mystery.
