Ascalon, Platinum Sword of Bahamut

The sword of Bahamut, Ascalon was forged and weaved by an expert and most trusted forge domain cleric of Bahamut using the very scales of the platinum dragon throughout the entire frame, from top to bottom, with radient blue energy visably pulsating through the swords etchings on the hilt, patterns on the blade, and it's 2 jewels, one embedded in the center of the hilt in a diamond shape, the other spherical in shape embedded in the pommel. Ascalon's etchings are text written in draconic that display the swords current state of "legacy". Ascalons energy seems to also change color depending on the users current state of mind. This sword also starts to glow a bright light of blue energy when the sword is within 100 feet of a chromatic dragon or wyvern. This sword was forged with the intent to find and bond with a user worthy of Bahamut's attention and send them off towards the battle for justice and to face Tiamat and her followers. Per chance the current user of Ascalon dies or passess away of old age, the sword is returned to Bahamut and awaits for the sword's call for a new wielder, whether it is a champion of Bahamut or some commoner from the country side, the user must pick up the calls of Ascalon.
