Blade of the Sun Lord

Lore:
The blade is lined with three sun runes which radiate magic when a detect magic spell is cast upon the sword. The hilt is made from a black stone which seems to absorb sunlight during the day, and becomes warm to the touch at night when the blade is glowing.
Fact:
The Blade of the Sun Lord is considered a +1 longsword that is treated as a shortsword in terms of weight and size.
This blade bonds with an owner of good alignment after being attuned for one week. Once attuned, the blade will always attempt to return to its owner if lost or stolen. It will fall off wagons, slip out of sheaths, and find anyway possible to return. If the owner of the blade commits a single evil act the blade will abandon its owner in search of a more suitable candidate. The bond is severed with the owner's death.
If the blade is wielded by an evil character it crumbles to dust once exposed to direct sunlight. An evil character will know after 1hr of an attempted attunement that it will not benefit from this weapon and becomes ill and sickly upon holding it.
Characters level 1-6 which wield this blade obtain only the +1 bonus associated with it and none of the abilities. Once a character reaches 7th level or is attuned for an entire solar year, they become worthy of the Sun Lord's power and the full potential of the blade is unlocked.
