As he said, Umbra isn't leveled. Its still an original blade with soul trap.

Although, if you complete a lot of quests in low level you will still get the same items, the only thing changed on the items is the enchantment.
I mean, its still the same weapons but you'll do more damage with them as you level in the required skill :=)

*spoiler* One example is the chorrol recommendation for the mages guild; Fingers of the mountain.
I finished "part II" in that quest when I was level 28 and I got a spell so powerful that it costed 780energy points to cast. That is WAY more than it should.*spoiler*
