(Sorry for not saying so, but I feel asleep, but I'm awake now!)
(Given that the sword has now been made into a real sword, that's the ability you gave it, mainly increased sharpness, durability, and balance. If it had remained a imitation you could have added different powers that might have activated by swinging it or other actions. Looking at it changed the power, mainly because I don't want the legendary sword to be to OP, but because it is legendary there is one ability related to leadership that won't be usable for the time being.) (And I find through research that putting a gem as the pommel is difficult and makes the sword unbalanced, so keeping it balanced despite being physically impossible is another thing, but it's a story so whatever is fine)
Alfred continued to admire the new blade, but unknowing to him it was the same sword he created it had just been advanced to be a usable weapon. However without swordsmanship skills, it can only be used in a few ways.
The gem in the pommel was very secure with no chance to remove it, and it only served as decorative use, but it is very good at it's job for that matter. Getting up from the ground he began to inspect the area again.
With the dim lit room it would be unknown what time it was, and the cavern for the most part remained undisturbed. The only difference was there was a faint breeze blowing through the tunnel.
